Abstract
A semiconductor optical device includes a first facet bounding a first end of the semiconductor optical device. The semiconductor optical device further includes a waveguide having a first end proximate the first facet, the first end of the waveguide being tapered towards the first facet. The first facet has a curvature to increase modal reflectivity at a first interface at which the first end of the waveguide meets the first facet.
