Patent ID: 8213802

Claim:
An optical receiver, comprising: a first substrate; a demultiplexer disposed on the first substrate, the demultiplexer having an input and a plurality of outputs, the input configured to receive a wavelength division multiplexed (wdm) optical input signal having a plurality of channels, each of said plurality of channels corresponding to one of a plurality of wavelengths, each of the plurality of outputs configured to supply a corresponding one of said plurality of channels; a first optical waveguide array disposed on the first substrate, said first optical waveguide array having a plurality of inputs, each of said inputs of the first optical waveguide array configured to receive a corresponding one of said plurality of channels; a second substrate; and an optical detector array disposed on the second substrate, the second substrate being in signal communication with the first substrate, the optical detector array having a plurality of inputs, each of which is configured to receive a corresponding one of said plurality of channels and generate an electrical signal in response thereto, wherein the first substrate further includes: a mirror disposed at an end of each waveguide of the first waveguide array, the mirror configured to redirect an optical signal received from the optical processor to the optical detector array disposed on the second substrate.
