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： An optical device includes a waveguide immobilized on a base. The device includes a port configured to receive light signals from the waveguide such that the light signals travel through the port. The light signals enter the port traveling in a first direction. The port is configured to change the direction of the light signals from the first direction to a second direction that is toward a location above the device or below the device. The device also includes a wedge configured to receive the light signals from the port such that the light signals travel through the wedge and then exit the wedge traveling in a direction that is at an angle in a range of 88° to 92° relative to the device and that is toward a location above or below the device.

摘要： Forming an optical device includes growing an electro-absorption medium in a variety of different regions on a base of a device precursor. The regions include a component region and the regions are selected so as to achieve a particular chemical composition for the electro-absorption medium included in the component region. An optical component is formed on the device precursor such that the optical component includes at least a portion of the electro-absorption medium from the component region. Light signals are guided through the electro-absorption medium from the component region during operation of the component.

摘要： The optical device includes an active component on a base. The active component is a light sensor and/or a light modulator. The active component including an active medium that includes a ridge and slab regions. The ridge extends upwards from the base and is positioned between the slab regions. The ridge defines a portion of a waveguide on the base. One or more isolation trenches each extends into the slab regions of the active medium and is at least partially spaced apart from the ridge of the active medium.
