Abstract:
Optical alignment of optical subassembly and optoelectronic device is achieved using an external source and an external receiver, passing optical signal through a passive waveguide in the optoelectronic device, via alignment reflective surface features provided on the optical subassembly. The optical subassembly is provided with a first alignment reflective surface directing alignment signal from the source to a grating coupler at the input of the waveguide, and a second alignment reflective surface directing to the receiver the alignment signal directed from a grating coupler at the output of the waveguide after the alignment signal has been transmitted from the input to the output through the waveguide. By adjusting the relative position between the optical subassembly and the optoelectronic device, and detecting the maximum optical power of the alignment signal reflected from the second alignment reflective surface, the position of best optical alignment of the optical subassembly and the optoelectronic device can be determined.

Claim (Index 1):
An optoelectronic structure, comprising:\n an optoelectronic device, wherein the optoelectronic device comprises an optical alignment waveguide outside an active region of the optoelectronic device, wherein the alignment waveguide includes an input alignment grating coupler and an output alignment grating coupler; and an optical subassembly, comprising a body having a first alignment reflective surface and a second alignment reflective surface, wherein the first alignment reflective surface is configured to be accessible to an external optical source of an alignment optical signal, wherein the first alignment reflective surface reflects the alignment optical signal to the input alignment grating coupler, and the output alignment grating coupler directs the same alignment optical signal to the second alignment reflective surface, and wherein the second alignment reflective surface is accessible to an external optical receiver of the alignment optical signal.
