Abstract:
1. A method for forming a semiconductor optical device comprising: providing an insulating layer having a surface; forming a light emitting fin region on the surface of the insulating layer that has a height that is greater than a width thereof; forming a conformal semiconductor layer overlying and adjacent the light emitting fin region; doping the conformal semiconductor layer using two angled implants of opposite conductivity type and respectively angled to opposite sides of the light emitting fin region; partially removing the conformal semiconductor layer adjacent the light emitting fin region and removing the conformal semiconductor layer above the light emitting fin region, the partially removing leaving a remainder thereof which is used to form a first light emitting fin sidewall electrode having a first conductivity type on the insulating layer and contacting a first side of the light emitting fin region, and form a second light emitting fin sidewall electrode having a second conductivity type on the insulating layer and contacting a second side of the light emitting fin region, the second side opposite the first side.
