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 13):
The photonics chip of  claim 1  wherein the at least one port layer further comprises a second port waveguide for connecting to the external optical system at the first wavelength \u03bb 1  or a third wavelength \u03bb 3 , and wherein the first device waveguide comprises a second coupling portion disposed to be optically coupled with the second port waveguide at the first wavelength \u03bb 1  or third wavelength \u03bb 3  while being optically decoupled from the first device waveguide at the second wavelength \u03bb 2 .
