Abstract
A laser receiver device and an associated input coupler are provided. In this regard, a chip-scale laser receiver device is provided that includes an input coupler that is configured to receive a gaussian beam. The input coupler includes a first waveguide having an optically-transparent material and a second waveguide coupled to the first waveguide. The second waveguide has a tapered configuration that tapers to a predetermined width across a length of not less than 500 micrometers. The input coupler further includes a third waveguide coupled to the second waveguide. The third waveguide has a tapered configuration that tapers to a predetermined width across a length of not less than 250 micrometers. The chip-scale laser receiver device further includes a bus optical waveguide coupled to receive a signal output from the input coupler, and to output a wavelength-multiplexed laser signal.
