摘要

我们提出了一种基于inp的y -耦合[1]激励谐振腔激光器。这种设计允许减少增益饱和和双光子吸收[2]。这是通过增加激光模式的横截面(降低场强)而实现的，同时保持单空间模式操作，这在许多半导体激光器应用中非常重要。这种设计既可以应用于宽波导激光器[3]，也可以应用于SCOWL(板耦合光波导激光器)[4]。

Reduction of gain-saturation in merged beam lasers

We present an InP-based laser with Y-coupling [1] inspired resonator cavity. This design allows the reduction of gain-saturation and two-photon absorption [2]. This is achieved by increasing the cross-section of laser mode (reducing the field intensity) while maintaining single spatial mode operation, which is very important in numerous semiconductor laser applications. This design can be applied to wide-waveguide lasers [3], as in this work, as well as to SCOWL (slab-coupled optical waveguide laser) [4].
