Claim:
1. A hybrid diode structure comprising: a substrate comprising single crystal silicon material; a buried oxide layer directly overlying and coupled to the substrate; a III-V diode, directly overlying and coupled to the oxide layer, and having an n-type region and a p-type region, wherein the p-type region is of a width and a height sufficient to create substantial mode confinement for an optical mode propagating therethrough; a first electrical contact electrically coupled to the n-type region; a second oxide layer directly overlying the III-V diode; a III-V conductive element passing through the second oxide layer and electrically coupled to the p-type region, wherein the III-V conductive element is reduced in width from the width of the p-type region such that optical losses are reduced by separating the second electrical contact from the optical mode; and a second electrical contact electrically coupled to the p-type region; wherein the optical mode propagates through a ridge portion of the p-type region: the III-V conductive element couples with the p-type region along substantially an entire length of the ridge portion of the p-type region along a direction of light propagation from the first silicon waveguide section to the second silicon waveguide section.
