Traditional RGB pixels are placed on a single plane, which limits the resolution. To overcome this, vertically stacked RGB pixels using heterogeneous and monolithic 3D integration (M3D) have been explored. However, previously reported vertical µLED pixels have not considered the heat dissipation capability of the pixels, which is indeed important in future micro displays, and utilized materials incompatible with standard CMOS processes, further limiting their practicality for LEDoS. The critical regions for constraint, the bonding medium, are typically organic polymer materials. Therefore, to handle issue, vertically stacked full‐color µLEDs are demonstrated using silicon oxide (SiO2) and yttrium oxide (Y2O3), as bonding mediums. These materials are CMOS‐compatible and offer thermal conductivity at least 10 times higher than conventional polymers. The InGaN/GaN blue µLEDs bonded with oxides show improved thermal management, leading to higher external quantum efficiency (EQE) and better color characteristics, including narrower full width at half maximum (FWHM) and higher color purity. Precise control over bonding layer thickness is achieved, minimizing pixel thickness and enhancing manufacturability for high‐resolution displays.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"22 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143853308","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, traditional EM selective structures suffer from increasingly severe characteristic impedance mismatches under the large‐angle oblique incidence of EM waves. To overcome this dilemma, a polarization‐insensitive uniaxial dielectric‐magnetic metasurface is proposed with ultrawide Brewster angle stability to realize perfect radiofrequency transparency. It is theoretically demonstrated that a uniaxial dielectric‐magnetic slab can exhibit ultra‐wide‐angle transmission properties while maintaining polarization insensitivity. As a proof of concept, a uniaxial dielectric‐magnetic metasurface structure is designed, fabricated, and measured to simultaneously achieve wide‐band and wide‐angle radiofrequency transparency phenomena with transverse electric and transverse magnetic polarization responses. This study fundamentally resolves the theoretical challenge of characteristic impedance mismatch in traditional EM surfaces under large‐angle oblique incidence, achieving an unprecedented realization of ultrawide angular, high‐efficiency transmission for arbitrarily polarized electromagnetic waves.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"120 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143853306","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}

This methodology is particularly advantageous in ultrafast lasers, where increasing output intensity is crucial. Here it is found that the thermo-optic effect, typically considered detrimental to laser performance, can instead promote mode transformation, enabling single-mode output from a multimode amplifier. Specifically, through thermal modulation, a 39% increase in output power, reaching 50 W of fundamental-mode output and a pulse width of 168 fs, in a multimode regenerative amplifier based on a Yb:CaAlGdO4 medium—establishing a new power benchmark for this system is achieved. In addition, to validate the general applicability, the technique to a Yb:YAG gain medium, achieving a 43% power enhancement and demonstrating effective single-mode transformation is extended. The demonstrated approach can be generalized to a broad range of laser gain media for power enhancement without additional optical components or design complexities.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"23 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143849514","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}

In this study, a 1D TIS-extended photonic crystal (1D-TISE-PhC) structure both theoretically and experimentally is demonstrated. a linearly dispersive, zero-index 1D photonic crystal is integrated with a four-phase shift (4PS) sampled grating so that photons propagate through the cavity without phase differences, enhancing robustness and extending the TIS. This extension yields a more uniform photon distribution along the laser cavity and mitigates spatial hole burning. This is fabricated and characterized a 1550 nm 1D-TISE-PhC semiconductor laser, achieving stable single-mode operation from 60 to 420 mA, with a side-mode suppression ratio of 50 dB. The device exhibited a linewidth narrowing effect, with the narrowest Lorentzian linewidth of 126 kHz and a typical linewidth of 150 kHz, nearly an order of magnitude lower than conventional distributed feedback Bragg lasers. Using reconstruction equivalent-chirp technology with the 4PS grating allowed precise wavelength control in laser arrays, with a spacing of 0.796 nm ± 0.003 nm. This results confirm that the TIS remains intact in the TISE cavity, preserving topological protection and demonstrating improved design simplicity and fabrication tolerance for high-power, narrow-linewidth semiconductor lasers.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"116 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143849513","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 considerable progress, blue QLEDs, especially those based on nonheavy metal materials, continue to face significant challenges in efficiency and stability, falling behind their red and green counterparts. Herein, a new strategy is presented to enhance the performance of ZnSeTe-based blue QLEDs by introducing SnO2 nanoparticles (NPs) prepared via freeze-drying technology as a conductive interlayer between the quantum dot (QD) layer and ZnO electron transport layer (ETL). This approach improves the dispersion of SnO2 NPs, reduces film surface roughness, and effectively suppresses device leakage currents. Furthermore, the freeze-drying process minimizes oxygen vacancies in SnO2 and reduces exciton quenching at the QD/ETL interface. As a result, the ZnSeTe-based blue QLEDs utilizing the freeze-dried SnO2 NP interlayer achieve a maximum external quantum efficiency (EQE) of 20.8%, a peak brightness of 6017 cd m−2, and a T50 operational lifetime of 130.7 h at a brightness of 100 cd m−2. These findings represent a significant improvement in the efficiency and stability of environmentally friendly blue QLEDs and provide valuable insights for advancing QLED technology.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"6 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143841466","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}
