Publication number: 20210028323Abstract: 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.Type: ApplicationFiled: October 7, 2020Publication date: January 28, 2021Inventors: Erik Johan Norberg, Anand Ramaswamy, Brian Robert Koch

Publication number: 20210026067Abstract: Described are various configurations of optical structures having asymmetric-width waveguides. A photodetector can include parallel waveguides that have different widths, which can be connected via passive waveguide. One or more light absorbing regions can be proximate to the waveguides to absorb light propagating through one or more of the parallel waveguides. Multiple photodetectors having asymmetric width waveguides can operate to transduce light in different modes in a polarization diversity optical receiver.Type: ApplicationFiled: September 25, 2020Publication date: January 28, 2021Inventors: Jonathan Edgar Roth, Jared Bauters, Erik Johan Norberg
