Abstract:
1. An optoelectronic device on a substrate comprising: a rib waveguide comprising: a first region of silicon formed on the slab of monocrystalline silicon along a first side of the rib, separated from the rib by a first region of dielectric, a second region of silicon formed on the slab of monocrystalline silicon along a second side of the rib, separated from the rib by a second region of dielectric, a plurality of doped regions in the slab of monocrystalline silicon, where a first and second doped region of the plurality of doped regions each respectively include the first and second regions of silicon, and a plurality of electrical contacts, where at least first and second electrical contacts are formed in respective first and second regions of silicon.
