摘要

我们研究了基于InAs/InP量子冲刺的广域和脊波导激光器,其发射波长高达2um。此外,还讨论了一种基于仿真的横向耦合DFB/DBR激光器设计,并对实现该设计的工艺步骤进行了优化。该设计与现成的加工技术完全兼容,并且能够实现足够高的耦合系数,以实现可调谐的横向耦合DBR (LC-DBR)激光器,而不需要在波纹基板上采用任何再生步骤,用于传统的DBR激光器。

Quantum dash based lasers for gas sensing
We present results on InAs/InP quantum dash based broad area and ridge-waveguide lasers with emission wavelength up to 2 um. In addition a simulation-based design for laterally coupled DFB/DBR lasers is discussed, and the optimization of the processing steps for the realization of this design is presented. The design is fully compatible with readily available processing techniques and enables sufficiently high coupling coefficients for the realization of a tunable laterally coupled DBR (LC-DBR) laser, without the need of employing any regrowth steps over corrugated substrates, used for conventional DBR lasers.
