Abstract: An optical receiver may include a planar lightwave circuit with an optical path and a tapered reflection surface to direct an optical beam toward a top surface of the planar lightwave circuit. The optical receiver may include a photodiode disposed onto the top surface of the planar lightwave circuit such that a receive portion of the photodiode is aligned to the optical path, wherein a gap between the photodiode and the planar lightwave circuit is less than 5 microns.

Abstract: An optical device includes a waveguide device and a fiber stub. The fiber stub at least partially contains a first optical fiber and is directly attached to the waveguide device by an adhesive. The first optical fiber is to be coupled to a second optical fiber included in an optical connector when the optical connector is inserted into a receptacle of the optical device. The fiber stub is to couple the first optical fiber to at least one of the waveguide device or an optical waveguide included in the waveguide device.
