摘要： An optical device includes a light-transmitting medium on a base. The light-transmitting medium at least partially defines a free propagation region through which light signals travel. A reflective grating is positioned such that light signals can travel through the free propagation region and be received by the optical grating. The optical grating is configured to reflect the received light signal back into the free propagation region. The optical grating reflects the light signals such that light signals associated with different wavelengths separate as the light signals travel through the free propagation region. The portion of the light-transmitting medium that defines the free propagation region has a facet through with the light signals are transmitted. The grating includes a buffer layer between the facet and a reflecting layer that is configured to reflect the light signals received by the grating.

摘要： A method of forming an optical device includes generating a device precursor having a layer of a light-transmitting medium on a base. The method also includes forming an etch stop on the layer of light-transmitting medium. An active medium is grown on the etch stop and on the light-transmitting medium such that the light-transmitting medium is between the base and the grown active medium. The grown active medium is etched down to the etch stop so as to define a ridge in the active medium. The ridge of active medium defines a portion of a component waveguide that will guide a light signal through an active component on the device.

摘要： A device includes an input waveguide on a base. The input waveguide guides a light signal through a light-transmitting medium to a light sensor. The light sensor includes a sensor waveguide on the base. The sensor waveguide includes a light-absorbing medium that receives the light signal from the input waveguide. The light-absorbing medium has one or more continuous doped regions that are each positioned such that an application of electrical energy to the doped regions forms an electrical field in the light-absorbing medium. One or more of the doped regions has a first portion that is located within the light-absorbing medium and a second portion located outside of the light-absorbing medium. The device also includes an electrical conductor for applying the electrical energy to one of the doped regions. The electrical conductor contacts the portion of the doped regions that is located outside of the light-absorbing medium.
