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 16):
A method for blocking a second wavelength from a device layer of a photonic chip that is configured to operate at a first wavelength, the method comprising:\n forming a port waveguide for connecting to an external system in a second layer of the photonic chip that is disposed over or under the device layer in a direction perpendicular to the device layer, the external system comprising a source of the second wavelengths; and, optically coupling the port waveguide to a device waveguide disposed in the device layer in a wavelength selective manner so that the device waveguide is optically coupled to the port waveguide at the first wavelength \u03bb 1  but is substantially optically decoupled at the second wavelength \u03bb 2 , so that the second wavelengths \u03bb 2  received in the port waveguide remains in the port waveguide without being coupled into the device layer.
