Abstract
Embodiments of the invention are hybrid photonic devices including a first semiconductor slab (i.e. region) comprising a silicon material and a second semiconductor slab, comprising a III-V material, above and partially overlapping the first semiconductor slab to create a lateral overlap region. A bonding layer may be formed on the second semiconductor slab to enable the bonding of the first and second semiconductor slabs at the lateral overlap region. An optical waveguide is formed to be included in the lateral overlap region and comprising the silicon semiconductor material, the III-V semiconductor material and the bonding layer. Thus, in embodiments of the invention the bonding layer comprises a material with a refractive index of at least 2.0 so as to not affect the optical mode shape or propagation loss of the hybrid electro-optical device.
