Abstract

A summary of recent progress towards the realization of fast tunable heterogeneously integrated InP-on-SOI laser diodes is presented. DFB and DBR laser structures comprising tunable twin-guide (TTG) InP membranes on SOI are discussed. Preliminary measurement results indicate promising static and dynamic lasing characteristics with self-heating being the limiting factor for fast wavelength tuning. Approaches to enhance the overall performance and modal overlap with the tuning layer are discussed, which should dramatically improve the lasing characteristics and tuning speed in future devices.
