    Abstract: An optical, directional coupler has a first input, a second input, a first output, and a second output. The coupler is made with a shoulder disposed on a substrate and a first ridge and a second ridge disposed on the shoulder. The first ridge extends from the first input to the first output. The second ridge extends from the second input to the second output. The shoulder, the first ridge, and the second ridge taper to provide coupling and are modified to select a coupling ratio. Further, a tunable laser has a first mirror, a second mirror, a gain medium, and a directional coupler. The first mirror and the second mirror form an optical resonator. The gain medium and the directional coupler are, at least partially, in an optical path of the optical resonator. The directional coupler provides an output coupler for the tunable laser.

    Abstract: A waveguide coupler has a compression region and an expansion region for coupling light between a silicon waveguide and an optical fiber. The compression region receives light from the silicon waveguide and compresses an optical mode of the light. Light is transmitted from the compression region to an expansion region. The expansion region expands the light to have a larger cross section. Light is then transmitted to the optical fiber.
