Abstract
A light emitting device, a transmitter, and a silicon photonics chip, among other things, are disclosed. An illustrative light emitting device is disclosed to include a silicon substrate, a waveguide disposed on or integrated in the silicon substrate, where the waveguide includes a wide waveguide section at a first end and a narrow waveguide section at a second end, a first metal pad disposed over the wide waveguide section and at least partially across the first end of the waveguide, and a second metal pad disposed over the wide waveguide section, distanced away from the first metal pad. Electrical current passing between the first metal pad and the second metal pad may cause light to be produced in the wide waveguide section and the light produced in the wide waveguide section is at least partially reflected by the first metal pad and directed to the narrow waveguide section for transmission.
