Abstract

In this paper we report on the observation of reflection values <-50dB at activepassive butt-joint interfaces in extended cavity Fabry-Pérot lasers and 0.19dB loss at passive-passive butt-joint interfaces. A three step growth process has been developed using MOVPE with all metal-organic precursors. In the first epitaxy step, the active layer stack is grown up to 200 nm above the index guiding layer. The passive regions are etched using a SiNx mask, afterwards those regions are re-grown up to the top of the active regions. Finally the SiNx mask is removed and the top cladding is grown. We have investigated the minimization of the butt-joint reflection by crossing the interface at different angles. Measurements showed that the butt-joint reflection is below -50dB for angles above 12 degrees.
