Abstract

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.
