Abstract
Embodiments of the invention describe apparatuses, optical systems, and methods related to utilizing optical cladding layers. According to one embodiment, a hybrid optical device includes a silicon semiconductor layer and a III-V semiconductor layer having an overlapping region, wherein a majority of a field of an optical mode in the overlapping region is to be contained in the III-V semiconductor layer. A cladding region between the silicon semiconductor layer and the III-V semiconductor layer has a spatial property to substantially confine the optical mode to the III-V semiconductor layer and enable heat dissipation through the silicon semiconductor layer.
Claims20
An semiconductor device with a waveguide, comprising:
- a cladding layer defining a longitudinal direction transverse to a surface of the cladding layer and a lateral direction parallel to the cladding layer, the cladding layer having a thinner lateral region and a thicker lateral region;
- a silicon semiconductor layer positioned on another surface of the cladding layer opposite the surface of the cladding layer;
- and
- a III-V semiconductor layer positioned on the surface the cladding layer, the III-V semiconductor layer having an active region with light confined in the III-V semiconductor layer by the thicker lateral region of the cladding layer.
