Latest Patents
One of his latest patents is titled "Optical coupler having segmented waveguides for coupling electromagnetic field." This invention describes a semiconductor photonic device that includes a substrate, facet(s), and optical coupler(s) associated with the facet(s). Each optical coupler is designed to couple an electromagnetic field incident on the respective facet towards a buried waveguide as the electromagnetic field proceeds into the semiconductor photonic device. The couplers feature waveguides that extend in a longitudinal direction and are at least partly encapsulated within a cladding layer. In some examples, at least one waveguide tapers along its length, and others include spaced-apart segments arranged to form a subwavelength grating (SWG) configured to entrain electromagnetic radiation.
Another notable patent is simply titled "Optical coupler."
