Abstract: There is disclosed in one example a fiberoptic communication circuit for wavelength division multiplexing (WDM) communication, including: an incoming waveguide to receive an incoming WDM laser pulse; an intermediate slab including a demultiplexer circuit to isolate n discrete modes from the incoming WDM laser pulse; n outgoing waveguides to receive the n discrete modes, the outgoing waveguides including fully-etched rib-to-channel waveguides; and an array of n photodetectors to detect the n discrete modes.
