Abstract

An optical receiver includes a first substrate including a demultiplexer and a first optical waveguide array. An input of the demultiplexer is configured to receive a wavelength division multiplexed optical input signal having a plurality of channels. Each of the plurality of channels corresponds to one of a plurality of wavelengths. Each of the plurality of outputs is configured to supply a corresponding one of the plurality of channels. The first optical waveguide array has a plurality of inputs. Each of the inputs of the first optical waveguide array is configured to receive a corresponding one of the plurality of channels. A second substrate is in signal communication with the first substrate and includes an optical detector array. The optical detector array has a plurality of inputs, each of which is configured to receive a corresponding one of the plurality of channels and generate an electrical signal in response thereto.
