摘要
理论分析并制备了1.31 μm正方形-Fabry-Perot(FP)耦合腔半导体激光器,其中正方形腔作为FP腔的一个反射端面,其反射率可以通过改变注入正方形腔的电流调节。正方形模式和FP模式之间的模式耦合能够抑制其他边模,易于实现单模激射。实验获得的单模激射边模抑制比最高为38 dB,其波长调谐范围为6 nm,估算的器件特征温度T0为46 K。
Abstract
A 1.31 μm square-Fabry-Perot (FP) coupled cavity semiconductor laser is theoretically analyzed and experimentally prepared. The square cavity acts as a reflection end for the FP cavity, and its reflectivity is adjustable by changing the current injected into the square cavity. The mode coupling between the square mode and the FP mode can suppress other side modes, and it is easy to realize single-mode lasing. The maximum single-mode lasing side mode suppression ratio obtained in the experiment is 38 dB, the wavelength tuning range is 6 nm, and the estimated characteristic temperature T0 is 46 K.
