  Abstract:In this work, the concentration of rare-earth ions in doped silica whispering gallery lasers (WGLs) is controlled by evaporation. The fabrication of WGLs is used to experimentally evaluate the evaporation rate (mol/µm) and ratio (mol/mol) of erbium and silica lost from a doped fiber during heating. Fixed lengths of doped silica fiber are spliced to different lengths of undoped fiber and then evaporated by feeding into the focus of a CO2 laser. During evaporation, erbium ions are precipitated in the doped silica fiber to control the erbium concentration in the remaining SiO2, which is melted into a microsphere. By increasing the length of the undoped section, a critical point is reached where effectively no ions remain in the glass microsphere. The critical point is found using the spectra of the whispering gallery modes in microspheres with equal sizes. From the critical point, it is estimated that, for a given CO2 laser power, 6.36 × 10−21 mol of Er3+ is lost during the evaporation process for every cubic micron of silica fiber. This is equivalent to 1.74 × 10−7 mol of Er3+ lost per mol of SiO2 evaporated. This result facilitates the control of the doping concentration in WGLs and provides insight into the kinetics of laser-induced evaporation of doped silica. © 2024 Optica Publishing Group under the terms of the Optica Open Access Publishing Agreement.

  Abstract:The Pancharatnam–Berry (PB) phase has revolutionized the design of metasurfaces, offering a straightforward and robust method for controlling wavefronts of electromagnetic waves. However, traditional metasurfaces have fixed PB phases determined by the orientation of their individual elements. In this study, an innovative structural design and integration scheme is proposed that utilizes vanadium dioxide, a phase-change material, to achieve thermally controlled dynamic PB phase control within the metasurface. By leveraging the material's properties, this can dynamically alter the optical orientation of individual elements of the metasurface and achieve temperature-dependent local phase modulation based on the geometric phase principle. This approach, combined with advanced fabrication processing technology, paves the way for next-generation dynamic devices with customizable functions. © 2024 Wiley-VCH GmbH.

  Abstract:Random bit generators are critical for information security, cryptography, stochastic modeling, and simulations. Speed and scalability are key challenges faced by current physical random bit generation. Herein, we propose a massively parallel scheme for ultrafast random bit generation towards rates of order 100 terabit per second based on a single micro-ring resonator. A modulation-instability-driven chaotic comb in a micro-ring resonator enables the simultaneous generation of hundreds of independent and unbiased random bit streams. A proof-of-concept experiment demonstrates that using our method, random bit streams beyond 2 terabit per second can be successfully generated with only 7 comb lines. This bit rate can be easily enhanced by further increasing the number of comb lines used. Our approach provides a chip-scale solution to random bit generation for secure communication and high-performance computation, and offers superhigh speed and large scalability. © The Author(s) 2024.

  Abstract:Multi-angle polarization characteristics of water-leaving radiation, which contain rich information on oceanic constituents and inherent optical properties (IOPs), have often been neglected. In this study, global radiative transfer (RT) simulations for the polarization characteristics of water-leaving radiance (Lw) were performed using the vector radiative transfer model for a coupled ocean-atmosphere system (PCOART). And, a global polarization-based algorithm for retrieving oceanic constituents and inherent optical properties (IOPs) was developed, employing the Fully Connected U-Net (FCUN). The retrieval performance of the algorithm was then analyzed using in-situ measurements collected during the Qiandao Lake field campaign. Results indicated that the low degrees of polarization (DOP) at short blue bands at solar zenith angle of 0° predominantly occurred in the tropical and subtropical oceans, with the lowest DOP value of 0.0176 observed in the extra oligotrophic subtropical gyres. The global mean absolute percentage error (MAPE) of the FCUN predictions compared to RT simulations for oceanic constituents (Chla, ag(443), NAP) and IOPs (a, b, aph, bph, aNAP, bNAP, bb, bbph, bbNAP) at 443 nm were 6.24%, 3.90%, 10.65%, 2.85%, 3.15%, 3.79%, 4.42%, 3.90%, 3.90%, 3.13%, 4.44%, and 3.90%, respectively, with mean global MAPE values of 4.52%. Additionally, the FCUN model’s predictions were consistent with RT simulation inputs under various random instrument noise conditions, with mean global MAPE values of 6.74% and 8.84% for those 12 retrieved parameters, respectively. Moreover, the retrieval performance analysis of FCUN on the in-situ measurements was performed with MAPE for Chla, a, aph, bb at 443 nm of 31.80%, 29.65%, 34.87%, and 43.04%, respectively. The importance of multi-angles polarization observations of Lw for ocean constituents and IOPs retrieval were also examined with the global mean MAPE decreasing from 16.91% to 1.48% as the observation angles increasing. Overall, the global polarization-based inversion model exhibited substantial potential for the oceanic constituents and IOPs retrieval of using multi-angle polarimetry. © 2024, The Authors.

  Abstract:We demonstrate that two types of dark gap soliton families, the fundamental dark solitons and the dark soliton clusters, can be stabilized in coupled nonlinear Schrödinger equations (NLSEs) with linear lattices. Two types of coupled NLSEs are investigated, those with identical lattices and those with different lattices. In the latter case, one component features a monochromatic linear lattice, while the other features a bichromatic linear lattice. For coupled NLSEs with the same lattices, the soliton profiles are nearly identical, with both components exhibiting monochromatic backgrounds. In contrast, for coupled NLSEs with different lattices, the profiles differ significantly: one component has a monochromatic background, while the other has a bichromatic background. The stability domains of these dark soliton families are determined by the method of linear stability analysis, and also confirmed by direct numerical simulations. © The Author(s), under exclusive licence to Springer Nature B.V. 2024.

  Abstract:Non-line-of-sight (NLOS) imaging retrieves the hidden scenes by utilizing the signals indirectly reflected by the relay wall. Benefiting from the picosecond-level timing accuracy, time-correlated single photon counting (TCSPC) based NLOS imaging can achieve theoretical spatial resolutions up to millimeter level. However, in practical applications, the total temporal resolution (also known as total time jitter, TTJ) of most current TCSPC systems exceeds hundreds of picoseconds due to the combined effects of multiple electronic devices, which restricts the underlying spatial resolution of NLOS imaging. In this paper, an instrument response function deconvolution (IRF-DC) method is proposed to overcome the constraints of a TCSPC system s TTJ on the spatial resolution of NLOS imaging. Specifically, we model the transient measurements as Poisson convolution process with the normalized IRF as convolution kernel, and solve the inverse problem with iterative deconvolution algorithm, which significantly improves the spatial resolution of NLOS imaging after reconstruction. Numerical simulations show that the IRF-DC facilitates light-cone transform and frequency-wavenumber migration solver to achieve successful reconstruction even when the system s TTJ reaches 1200 ps, which is equivalent to what was previously possible when TTJ was about 200 ps. In addition, the IRF-DC produces satisfactory reconstruction outcomes when the signal-To-noise ratio (SNR) is low. Furthermore, the effectiveness of the proposed method has also been experimentally verified. The proposed IRF-DC method is highly applicable and efficient, which may promote the development of high-resolution NLOS imaging. © 2024 Optica Publishing Group (formerly OSA). All rights reserved.

  Abstract:Fourier ptychography (FP) imaging, drawing on the idea of synthetic aperture, has been demonstrated as a potential approach for remote sub-diffraction-limited imaging. Nevertheless, the farthest imaging distance is still limited to around 10 m, even though there has been a significant improvement in macroscopic FP. The most severe issue in increasing the imaging distance is the field of view (FoV) limitation caused by far-field conditions for diffraction. Here, we propose to modify the Fourier far-field condition for rough reflective objects, aiming to overcome the small FoV limitation by using a divergent beam to illuminate objects. A joint optimization of pupil function and target image is utilized to attain the aberration-free image while estimating the pupil function simultaneously. Benefiting from the optimized reconstruction algorithm, which effectively expands the camera’s effective aperture, we experimentally implement several FP systems suited for imaging distances of 12 m, 65 m, and 120 m with the maximum synthetic aperture of 200 mm. The maximum synthetic aperture is thus improved by more than one order of magnitude of the state-of-the-art works from the furthest distance, with an over fourfold improvement in the resolution compared to a single aperture. Our findings demonstrate significant potential for advancing the field of macroscopic FP, propelling it into a new stage of development. © 2024 Optica Publishing Group under the terms of the Optica Open Access Publishing Agreement.

  Abstract:The conventional pretraining-and-finetuning paradigm, while effective for common diseases with ample data, faces challenges in diagnosing data-scarce occupational diseases like pneumoconiosis. Recently, large language models (LLMs) have exhibits unprecedented ability when conducting multiple tasks in dialogue, bringing opportunities to diagnosis. A common strategy might involve using adapter layers for vision–language alignment and diagnosis in a dialogic manner. Yet, this approach often requires optimization of extensive learnable parameters in the text branch and the dialogue head, potentially diminishing the LLMs’ efficacy, especially with limited training data. In our work, we innovate by eliminating the text branch and substituting the dialogue head with a classification head. This approach presents a more effective method for harnessing LLMs in diagnosis with fewer learnable parameters. Furthermore, to balance the retention of detailed image information with progression towards accurate diagnosis, we introduce the contextual multi-token engine. This engine is specialized in adaptively generating diagnostic tokens. Additionally, we propose the information emitter module, which unidirectionally emits information from image tokens to diagnosis tokens. Comprehensive experiments validate the superiority of our methods. © 2024 Elsevier B.V.

  Abstract:Hypothetical axions provide a compelling explanation for dark matter and could be emitted from the hot solar interior. The CERN Axion Solar Telescope has been searching for solar axions via their back conversion to x-ray photons in a 9-T 10-m long magnet directed toward the Sun. We report on an extended run with the International Axion Observatory pathfinder detector, doubling the previous exposure time. The detector was operated with a xenon-based gas mixture for part of the new run, providing technical insights for future configurations. No counts were detected in the 95% signal-encircling region during the new run, while 0.75 were expected. The new data improve the axion-photon coupling limit to 5.8×10-11 GeV-1 at 95% CL (for ma0.02 eV), the most restrictive experimental limit to date. © 2024 authors.

  Abstract:The High Energy cosmic-Radiation Detection facility (HERD) will be a calorimetric experiment on board the China Space Station. Starting from 2027, HERD will perform the first direct measurement of cosmic rays in the PeV region and the gamma-ray full-sky survey from 100 MeV. The detector will be equipped with a scintillating-fiber tracker (FIT) read out with silicon photomultipliers. A miniature of a FIT sector, called MiniFIT, was designed, built and tested with particle beams at CERN. The FIT design, together with the design and physics performance of MiniFIT will be presented in this contribution. © Copyright owned by the author(s) under the terms of the Creative Commons.
