Abstract:
1. A hybrid optical apparatus comprising: a first semiconductor region including an active region of one or more layers of semiconductor materials; and a second semiconductor region coupled with the first semiconductor region, wherein the second semiconductor region includes an optical waveguide configured to transmit light inputted by a light input component coupled with the apparatus, and two or more trenches disposed substantially along a length of the apparatus and filled with gas or dielectric material having a refractive index below a threshold, wherein the optical waveguide is defined by a first trench of the two or more trenches disposed on a first side of the optical waveguide, and a second trench of the two or more trenches disposed on a second side of the optical waveguide opposite the first side of the optical waveguide, wherein a width of each trench varies along the length of the apparatus to control optical power density of the light transmitted along the optical waveguide, wherein the length of the apparatus is defined along a direction of light through the apparatus.
