摘要

波长为 1550 nm 的光子晶体表面发射激光器（PCSEL）在光通信和眼部安全传感应用中极具吸引力。在本研究中，我们介绍了基于 InP 的 PCSEL，其特点是采用双晶格光子晶体结构，专为 1550 nm 波长的高功率单模运行而设计。这些 PCSEL 在 25 °C 连续波条件下的输出功率超过 300 mW。此外，在 15 °C 至 60 °C 的温度条件下，验证了高度稳定的单模振荡，侧模抑制比超过 60 dB。光子带结构的测量和模拟揭示了阈值增益裕量和光耦合系数对单模稳定性的影响。

High-power, stable single-mode CW operation of 1550 nm wavelength InP-based photonic-crystal surface-emitting lasers

1550 nm wavelength photonic-crystal surface-emitting lasers (PCSELs) are attractive for optical communication and eye-safe sensing applications. In this study, we present InP-based PCSELs featuring a double-lattice photonic-crystal structure designed for high-power single-mode operation at a wavelength of 1550 nm. These PCSELs demonstrate output powers exceeding 300 mW under continuous-wave conditions at 25 °C. Additionally, highly stable single-mode oscillation with a side-mode suppression ratio of over 60 dB is verified at temperatures from 15 °C to 60 °C. Measurement and simulation of photonic band structures reveal the impacts of the threshold gain margin and optical coupling coefficient on the single-mode stability.
