ABSTRACT:
A method for reducing surface recombination in an area next to a mesa in devices containing active and passive sections. This is obtained by growing, by metalorganic vapor phase epitaxy (MOVPE), a thin epitaxial layer of material with larger bandgap than a waveguide material and preferably smaller surface recombination rate than the waveguide material. This thin layer is preferably non-intentionally doped to avoid creating a surface leakage path, thin enough to allow for carrier to diffuse to and thermalize in the waveguide layer and thick enough to prevent carriers to tunnel through it.
