Abstract:
A method for on-wafer testing of optical structures of photonic chips that include edge couplers as input/out ports includes defining, in test a test area of the wafer, an edge coupler pair formed of two edge couplers separated by a test gap, which may have a width that is close to the width of a chip-fiber gap during normal operation of the photonic chips. Test areas may include chains of different numbers of the edge coupler pairs for determining coupling loss per edge coupler.

Claim (Index 12):
The A photonic wafer of  claim 1  comprising:\n a substrate; \n an optical layer supported by the substrate; \n a plurality of photonics chips defined upon the substrate so as to be spaced apart from each other, each photonic chip comprising an edge coupler that is defined at least in part in the optical layer and configured to be used for coupling light into or out of the photonic chip when the photonic chip is separated from the wafer; and, \n one or more test structures defined at least in part in the optical layer, each comprising one or more edge coupler pairs (ECPs), each of the one or more ECPs comprising two test edge couplers optically coupled across a test gap, wherein the test gap separates the two test edge couplers by a distance that is at most half of an edge-to-edge spacing between adjacent photonic chips; \n wherein the test gap widens away from an optical axis of the edge coupler pair so as to at least partially collimate or focus light propagating between the two test edge couplers thereof.
