ABSTRACT:
An apparatus and method providing a plurality of modulated optical beams from a single layer of semiconductor material. For one example, an apparatus includes a plurality of optical waveguides disposed in a single layer of semiconductor material. Each one of the plurality of optical waveguides includes an optical cavity defined along the optical waveguide. A single bar of gain medium material adjoining the single layer of semiconductor material across the plurality of optical waveguides is included. The gain medium-semiconductor material interface is defined along each of the plurality of optical waveguides. A plurality of optical modulators is disposed in the single layer of semiconductor material. Each one of the plurality of optical modulators is optically coupled to a respective one of the plurality of optical waveguides to modulate a respective optical beam directed from the optical cavity.
