Among them, discrete time crystals are recognized by the spontaneous generation of robust subharmonic oscillations. So far, most time crystals are restricted to exhibit a “period‐doubled” behavior. However, a fertile ground in time crystalline with period‐‐tupling has been suggested. Here we experimentally realize scalable period‐2‐tupling and period‐‐tupling in the one‐ (1D) and two‐dimensional (2D) photonic lattices, respectively. In this non‐interacting system, no spontaneous symmetry breaking occurs; instead, the period‐‐tupling arises from the preparation of specific superpositions of eigenmodes with quasienergy gaps of . All levels of the 2D spectrum are paired with different gaps, so that different response periods can be achieved by exciting different sites of the same lattice. The period ‐tupling is robust against perturbations over an extraordinarily long time evolution. The results may promote further research into arbitrary higher‐order time crystals in interacting photonic systems and into non‐equilibrium physics adopting Floquet driving. Next‐generation quantum devices, such as topologically protected quantum state registers, quantum sensors, and simulators, can also be inspired by this approach.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"20 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2026-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149208468","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}

Here we introduce Mie‐void metasurfaces operating in transmission, implemented using the silicon‐rich nitride (SRN) platform for visible‐range operation. We show that this transition is not a simple change in geometry: placing the voids in a finite film on a substrate introduces slab‐guided and Fabry–Pérot‐like contributions that hybridize with the underlying Mie‐void response. Rigorous coupled‐wave analysis shows that the dominant spectral transformation arises from replacing the semi‐infinite host with a finite SRN film, while the substrate acts as a secondary perturbation. Thickness‐dependent dispersion maps reveal an avoided crossing between interacting modes, identifying film thickness as a clean parameter for tracking the coupled modal evolution. Experimentally, we demonstrate depth‐dependent transmission spectra in good agreement with simulation, and realize visible structural colors and spatially encoded transmitted‐light patterns within a single metasurface architecture. These results establish transmission‐mode Mie‐void metasurfaces as a viable inverse‐dielectric platform for transmissive spectral filtering, optical encoding, and display‐oriented photonic elements.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"15 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2026-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149198998","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}

For the dual‐ring system, we show that the SIL region on the tuning curve splits into two distinct subregions, governed by the inter‐ring coupling coefficient and the central‐frequency detuning. Using the Turnkey method, we demonstrate spontaneous generation of single‐soliton combs, and achieve a conversion efficiency of 60% in a Vernier dual‐ring configuration with an FSR ratio of 5.1. For the interferometric microring (U‐shaped feedback arm), we show that SIL enables high‐probability reproducible generation of soliton crystals with pulse numbers tunable from 4 to 8 via the transmission phase, with conversion efficiencies ranging from 67% to 88%. The upper limit of the soliton number can be further extended by dispersion engineering. In addition, repeated Turnkey simulations reveal that SIL significantly biases the probability distribution of final soliton‐crystal states, and perturbation‐recovery tests demonstrate the robustness of the selected states against parameter fluctuations. We also observe that the SIL effect is nearly suppressed at specific circular phase configurations.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"188 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2026-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149198995","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}

By spatially shifting localized fields, P‐SALM achieves sub‐diffraction imaging with conventional fluorophores, without requiring photoswitchable dyes or high depletion intensities. In proof‐of‐concept experiments, four‐channel P‐SALM enabled visualization of pre‐synaptic VGAT and post‐synaptic MAP2 distributions in fixed hippocampal neurons by producing peak full‐width‐at‐half‐maximum of 42 nm (VGAT) and 55 nm (MAP2) as effective localization precision. While the current implementation yields an effective resolution of ∼130 nm and remains limited by fluorophore density and aperture geometry, the results demonstrate the feasibility of plasmonic near‐field modulation as an alternative pathway to super‐resolution. Compared with PALM, STORM, and STED, P‐SALM simplifies sample preparation and operates under relatively low excitation powers; relative to conventional SIM, it achieves resolution enhancement through sub‐diffraction limited near‐field rather than far‐field interference.

However, the realization of near‐infrared DKS in silicon has not been experimentally reported due to severe two‐photon absorption (TPA) and free‐carrier absorption (FCA). Here, we report the first experimental evidence for deterministic low‐noise soliton‐crystal (SC) states in monolithic silicon resonators operating at telecom wavelengths (1.55 µm). By synergistically combining an active lateral p–i–n junction for rapid free‐carrier extraction with precise spatial‐mode dispersion engineering, we overcome the nonlinear loss in silicon to achieve robust parametric oscillation. With this strategy, an avoided mode crossing provides deterministic pathways to SC states with 2‐FSR and 3‐FSR comb spacing, characterized by sech 2 envelope, distinct power steps and low radiofrequency (RF) noise. Separately, a near‐zero‐dispersion resonator produces broadband optical parametric oscillation (OPO) with cascaded sub‐comb formation spanning over 300 nm across the S, C, and L bands, distinct from the SC states. These results demonstrate telecom‐band nonlinear‐photonic comb generation in monolithic silicon, with potential for future co‐integration with silicon photonic and CMOS components.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"7 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2026-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149199016","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}

Here, we analyze the inelastically scattered light from ultrathin, time‐varying optical media and search for spectroscopic signatures of nonthermal phonon populations. Our approach targets hypersonic gigahertz (GHz) acoustic phonons, termed Lamb modes, confined in prototypical, submicron‐thick membranes: 260 nm‐thick bare silicon and bilayer structures with 50 nm‐thick gold layer on 200 nm‐thick silicon. Femtosecond laser irradiation of the membranes modulates their optical properties and excites nonthermal, coherent Lamb modes, which are probed via inelastic light scattering of a continuous‐wave laser beam. In metal‐semiconductor heterostructures, the anti‐Stokes signal of photoexcited Lamb modes undergoes blueshifting and an antiresonance‐to‐resonance temporal transition, which remains unobserved for Stokes scattering. This effect is attributed to inelastic interactions between thermoelastically excited acoustic phonons, resulting in an approximately 3.6% shift in the frequency of longitudinal acoustic phonons. Our work enables studies of heat transport, phonon dynamics, and optomechanics in time‐modulated systems, using principles from time‐varying optics.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"82 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2026-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149172603","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}

Their insufficient stability in complex environments further restricts practical applications. To overcome this bottleneck, a full‐site regulation strategy was implemented based on a novel CaY 2 Ga 4 SiO 12 : Cr 3+ garnet model. A “two‐ion, three‐site” synergistic regulation mechanism was proposed and verified for the first time. Through the synergistic co‐substitution of Li + and Ge 4+ , trans‐coordination migration and occupancy of ions were induced across three key sites: dodecahedral, octahedral, and tetrahedral. This atomic‐scale site reconstruction was directly observed via aberration‐corrected transmission electron microscopy (AC‐TEM). Combined with Density functional theory (DFT) calculations, it was confirmed that this multi‐site coordination mechanism reshapes the crystal field environment and enhances structural rigidity through a charge self‐compensation effect. This engineering drives the emission peak redshift to 810 nm while pushing the internal quantum efficiency (IQE) to 93%. Due to its superior optoelectronic properties, this material enables robust non‐line‐of‐sight (NLOS) optical communication through obstacles.
