However, the limited image quality and lengthy computational times for iterative reconstruction still hinder its practical application. Recently, single-pixel imaging based on deep learning has attracted a lot of attention due to its exceptional reconstruction quality and fast reconstruction speed. In this review, an overview of the current status, and the latest advancements of deep learning technologies in the field of single-pixel imaging are provided. Initially, the fundamental principles of single-pixel imaging and deep learning, followed by a discussion of their integration and associated benefits are presented. Subsequently, a comprehensive review is conducted on the advancements of deep learning in various domains of single-pixel imaging, covering super-resolution single-pixel imaging, single-pixel imaging through scattering media, photon-level single-pixel imaging, optical encryption based on single-pixel imaging, color single-pixel imaging, and image-free sensing.

However, in a PT-symmetry system with saturable absorption mechanisms, the random background noise can initiate single-mode oscillation at any of the maxima within the gain spectrum, that is, potential PT frequencies. Such randomness impedes the acquisition of high-quality signals at desired frequencies. Here, this work proposes a method to obtain deterministic PT-symmetry single-mode oscillation in a filterless multimode resonator through one-shot injection. With this technique, this work changes the system's gain spectrum and enhances the gain discrepancy. Utilizing the frequency domain saturable absorption of the resonator, oscillation at desired mode can maintain its frequency after the withdrawal of the injection signal. To validate the concept, this work establishes a polarization-division multiplexed dual-loop optoelectronic oscillator (OEO) with a 1-km long cavity operated under PT-symmetry conditions. By one-shot injecting the PT-OEO, this work effectively eliminates the randomness arising from the relatively flat gain spectrum, facilitating oscillation at any desired potential PT frequencies from 1.8 to 9 GHz without requiring elaborate frequency tuning structures. Moreover, the one-shot injection technique produces ultra-low phase noise performance, achieving a remarkable −158.6 dBc Hz−1@10 kHz. This performance level stands in close comparison with the best phase noise values recorded for OEOs.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"17 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2024-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142793298","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, despite significant advancements in fluoride and chalcogenide fiber platforms, realizing mid-infrared Raman soliton lasers on on-chip platforms remains challenging. In this study, the first experimental demonstration of a mid-infrared Raman soliton laser in an on-chip Ge28Sb12Se60 (GeSbSe) chalcogenide glass waveguide is presented. A fully fiberized femtosecond fiber laser, centered at 1.96 µm and emitting 246 fs pulses at a 50 MHz repetition rate, is utilized as the pump source, establishing a fiber-to-chip configuration. The waveguides are meticulously fabricated using e-beam lithography and plasma etching, achieving high optical quality and precision in the mid-infrared regime. Through precise geometrical dispersion engineering, a Raman soliton laser is achieved that continuously tunes from 1960 to 2145 nm within a 32.5 mm long snakelike GeSbSe strip waveguide. The threshold for pump peak power is remarkably low, at just 14.1 W (3.47 pJ). Additionally, a more than one-octave-spanning near to mid-infrared supercontinuum (1320–2760 nm at 22.9 pJ), reinforced by the combined Kerr and Raman effects, is also realized, confirming the versatile performance of the proposed GeSbSe waveguide. These findings pave the way for mid-infrared on-chip Raman soliton lasers, highlighting their potential for power-efficient, low-cost, and field-deployable on-chip applications in the mid-infrared regime.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"20 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2024-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142793300","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the lack of a uniformly distributed continuous emission spectrum in conventional WLED can result in “blue overshoot” and “cyan gap”, thus cause retinal damage and low color rendering index (CRI). Herein, a novel “kill two birds with one stone” strategy is reported: by preparing BaClF/CsPbBr3 heterostructures via a lattice- matching approach, F and Cl in BaClF matrix passivate the bromine vacancies of CsPbBr3 NCs, enhancing luminescence stability and achieving a blue-shift of PL to obtain cyan-emission. BaClF/CsPbBr3 heterostructures with controllable emissions in 468–510 nm can be fabricated by adjusting the molar ratios of CsPbBr3 to BaClF, and the photoluminescent quantum yield (PLQY) is up to 80.6%. The cyan-emitting BaClF/CsPbBr3 heterostructure acting as a cyan color converter can effectively absorb the “blue overshoot” and fill the “cyan gap” in WLED, thus significantly increasing the CRI value of WLED from 70.1 to 86.2 and the luminescent efficiency boosts from 21.3 to 87.8 lmW−1. This work highlights a lattice-matching strategy to produce ultra-stable cyan-emitting perovskite nanomaterials with high brightness and durability, paving the way for the application of perovskite NCs in next-generation WLED lighting.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"28 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2024-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142793301","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Various configurations of nanostructured Au interlayers are fabricated via solid-state dewetting, significantly enhancing the optoelectronic and pyroelectric properties of the original p-Si/CdS system. The p-Si/Au nanoparticles/CdS detector achieves a responsivity of 0.47 A/W, a response time of 830 ns, a −3 dB bandwidth of 0.33 MHz, and human recognition distance of up to 2 m. The improvement in optoelectronic properties is attributed to enhanced light absorption resulting from multiple internal reflections and localized surface plasmon resonance, as well as an enhanced built-in electric field within the Au/CdS Schottky junction. The improvement in pyroelectric properties is related to enhanced polarization of CdS resulting from the interface polar symmetry, which not only improves the visible photoresponse at high pulsed light frequencies but also enables effective detection of human radiation. Additionally, the effects of body parts, vertical distance, and moving velocity on pyroelectric human recognition are systematically investigated.
