Abstract:
A photonic chip includes a device layer and a port layer, with an optical port located at the port layer. Inter-layer optical couplers are provided for coupling light between the device and port layers. The inter-layer couplers may be configured to couple signal light but block pump light or other undesired wavelength from entering the device layer, operating as an input filter. The port layer may accommodate other light pre-processing functions, such as optical power splitting, that are undesirable in the device layer.

Claim (Index 20):
The method of  claim 16  comprising using a semiconductor layer of the chip as the device layer, and a dielectric layer of the chip as the second layer.
