Title: WAVEGUIDE OPTOELECTRONIC DEVICE
Abstract:
A waveguide optoelectronic device comprising a rib waveguide region, and method of manufacturing a rib waveguide region, the rib waveguide region having: a base of a first material, and a ridge extending from the base, at least a portion of the ridge being formed from a chosen semiconductor material which is different from the material of the base wherein the silicon base includes a first slab region at a first side of the ridge and a second slab region at a second side of the ridge; and wherein: a first doped region extends along: the first slab region and along a first sidewall of the ridge, the first sidewall contacting the first slab region; and a second doped region extends along: the second slab region and along a second sidewall of ridge, the second sidewall contacting the second slab region.
