Abstract

Tilted-mirror facets have been introduced as a design alternative to antireflection coating for waveguide structures that require low facet reflectivity. We show that tilted-mirror facets with finite reflectivity can induce significant intermode coupling in semiconductor lasers and optical amplifiers. We describe the effect of tilt-induced intermode coupling on the cavity modes using a simple model and discuss the implications of our results on the design of tilted-mirror integrated-optical lasers and amplifiers.
