摘要

基于氮化镓的可见光波长光子晶体表面发射激光器（PCSEL）在材料加工、高亮度照明和显示等各种应用领域备受关注。在这封信中，我们展示了绿色波长的氮化镓基 PCSEL。我们在 p-GaN 中形成了光子晶体 (PC)，并用二氧化硅填充 PC 中的孔，以确保器件的稳定性。通过脉冲条件下的电流注入测试和光谱分析，我们证实所制造的器件在 505 nm 以上波长具有Γ点单模振荡。我们的研究成果有望进一步拓展 PCSEL 和半导体激光器在可见光区域的应用。

Green-wavelength GaN-based photonic-crystal surface-emitting lasers

Visible-wavelength GaN-based photonic-crystal surface-emitting lasers (PCSELs) have attracted attention for various applications, such as materials processing, high-brightness illuminations, and displays. In this letter, we demonstrate GaN-based PCSELs at green wavelengths. We formed a photonic crystal (PC) in p-GaN and filled holes of the PC with SiO2 to ensure device stability. Through a current injection test under pulsed conditions and spectral analysis, we confirmed that the fabricated device possessed Γ-point single-mode oscillation at wavelengths above 505 nm. Our results have the potential to further expand the applications of PCSELs and semiconductor lasers in visible region.
