摘要： The light sensor is included on an optical device having a waveguide on a base. The waveguide is configured to guide a light signal through a crystalline light-transmitting medium. The light sensor is also positioned on the base and is configured to receive the light signal from the waveguide. The light sensor includes a planar interface between two different materials. The interface is at a 45° angle relative to a direction of the light-transmitting medium.

摘要： An optical device includes an active component on a base. The active component is a light sensor and/or a light modulator. The active component is configured to guide a light signal through a ridge of an active medium extending upwards from slab regions of the active medium. The slab regions are on opposing sides of the ridge. The active medium includes a doped region that extends into a lateral side of the ridge and also into one of the slab regions. The depth that the doped region extends into the slab region is further than the depth that the doped region extends into the ridge.

摘要： An optical component is disclosed. The optical component includes a tap waveguide and a primary waveguide positioned on a base. The tap waveguide is configured to receive a portion of a light signal traveling along the primary waveguide. The portion of the light signal received by the tap waveguide is the tapped portion of the light signal. A direction changing region is configured to receive the tapped portion of the light signal from the tap waveguide and to direct the tapped portion of the light signal travels away from the base. A light sensor is configured to receive the tapped portion of the light signal from the direction changing region.

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.
