ABSTRACT:
A monolithic receiver photonic integrated circuit (RxPIC) chip includes a plurality of optical signal channels together with other active elements integrated on a semiconductor chip, which chips further include a wavelength selective decombiner comprising a supergrating or an Echelle grating which provides for a more compact chip compared to an integrated on-chip arrayed waveguide grating (AWG) functioning as a wavelength selective decombiner.
