While static luminescence dominates conventional applications, dynamic luminescent systems offer superior information capacity through spatiotemporal light evolution and multiplexing. However, this paradigm shift is hindered by activator paucity and similar luminescence kinetics that confine most systems to monochromatic intensity variations. Here, this chromatic stagnation is broken through a dynamic thermo‐stimulated luminescence (DTSL) platform exhibiting temperature‐gated temporal evolution of dual‐emission intensity ratios, enabling quantized and visible chromatic transitions from green→cyan→blue. It originates from the dynamic interplay between blue emission (derived from deep‐level oxygen vacancy centers) and green luminescence (generated by Eu2⁺ activators) and thus tunable relative intensity, under the premise of the concerted modulation of defect concentration and energy level positioning. Mechanism studies reveal that nonstoichiometric doping creates a hierarchical defect architecture, where controlled energy partitioning between deep and shallow defects governs the time‐resolved chromatic trajectory. Beyond establishing a general framework for dynamic luminescence design, the work rationally manipulates the fundamental relationship between defect architecture and photonic information, opening previously unfeasible multicolor DTSL avenues for optical multiplexing.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"51 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144565884","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}

Holographic displays can generate ideal 3D virtual images and have recently shown rapid advancements, particularly in noise reduction through learning‐based approaches. However, these displays still face challenges in improving image quality for AR scenarios because holographic virtual images are simply superimposed onto the real world, leading to a loss of contrast and visibility. To address this, occlusion optics, which can mask designated areas of the real world, is incorporated into holographic AR displays. The proposed system employs a folded 4f system with a digital micromirror device and sequentially operates as both a real‐world mask and an active Fourier filter. This approach transforms traditionally translucent holographic images into perceptually opaque ones while simultaneously eliminating unwanted noise terms from pixelated holographic displays. Furthermore, active Fourier filtering expands the virtual image field of view through time‐multiplexed operation and supports a novel binary hologram optimization algorithm that performs especially well for sparse virtual content. The implementation successfully achieves opaque holographic 3D image presentation, significantly improving contrast and image quality while producing highly realistic 3D AR scenes with optically cast shadows.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"93 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144565894","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}

Though the quality of eSWIR PbSe CQDs has been improved significantly, the PbSe CQD‐based photodiodes showed low external quantum efficiency (EQE) and poor stability under self‐driven photovoltaic mode, due to the residual reactive oxygen species (ROS) and carrier accumulation at interfaces. In this work, the ROS is removed by immerging the ZnO layer with 1,2‐ethanodithiol solvent before deposition of PbSe CQD layer, so that the storage stability of the photodiodes improved dramatically. On the other hand, a novel strategy is introduced to mitigate the carrier accumulation, in which a thin p‐type interlayer is inserted into the electron extraction interface. This strategy is universally effective in suppressing the carrier extraction barriers induced by Fermi level equilibration effects at interfaces. Finally, PbSe photodiodes achieve a record zero‐bias EQE of 17% in the eSWIR region. Due to the suppressed noise, the PbSe photodiodes in self‐driven mode demonstrate a specific detectivity of 5.7 Jones at the first excitonic peak of λ = 2.35 µm, which is comparable to self‐driven eSWIR photodiodes based on bulk InGaAs. Besides, this strategy also dramatically improved the working stability of the photodiodes.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"40 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144565886","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}

Conventional reconfiguration methods (thermo‐optic, free carrier dispersion, Pockels effect) often suffer from bulky sizes or high static power consumption, limiting scalability. We demonstrate, for the first time, a nonvolatile continuously tunable integrated optical router on a CMOS‐backend silicon‐on‐insulator (SOI) platform. This router employs Mach‐Zehnder optical switches with antimony sulfide (Sb₂S₃) phase shifters. Utilizing the Sb₂S₃ cell's nonvolatile phase change via a doped silicon microheater enables continuous forward switching and over 7 bits (128 levels) of reverse switching with zero static power. The nearly pure phase tuning capability of 0.3 dB/π achieves a high extinction ratio exceeding 18 dB. The phase shifter exhibits an insertion loss below 0.6 dB and endured over 1500 switching cycles using electrical pulses of varying voltage/duration for Joule heating. Additionally, the phase shifter supports MHz‐speed volatile switching via the thermo‐optic effect. This continuously tunable method provides superior precision over traditional non‐volatile multilevel techniques and effectively mitigates accumulated transmission errors in large‐scale Optical Network‐on‐Chip (ONoC) systems, removing a major obstacle to practical optical communication and computing implementation.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"48 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144566008","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}
