Abstract
An apparatus comprising a first photonic device comprising a waveguide loop configured to guide a first light from a first location of a surface to a second location of the surface, and a second photonic device comprising a light source configured to provide the first light, and a first alignment coupler optically coupled to the light source and configured to optically couple to the waveguide loop at the first location, a second alignment coupler configured to optically couple to the waveguide loop at the second location, and a photodetector optically coupled to the second alignment coupler and configured to detect the first light when the waveguide loop is aligned with the first alignment coupler and the second alignment coupler, and generate, based on the detection and on the received light, an electrical signal.
