摘要： An optical receiver has a monolithically integrated electrical and optical circuit that includes a substrate with a planar surface. Along the planar surface, the monolithically integrated electrical and optical circuit has an optical hybrid, one or more variable optical attenuators, and photodetectors. The optical hybrid is connected to receive light beams, to interfere light of said received light beams with a plurality of relative phases and to output said interfered light via optical outputs thereof. Each of the one or more variable optical attenuators connects between a corresponding one of the optical outputs and a corresponding one of the photodetectors.

摘要： A free-space optical switch for switching light beams between waveguides of planar lightwave circuits (PLCs). Switching is accomplished using a combination of lenses and micromirrors. The lenses and the controlled tilt of the micromirrors can establish a one-to-one interconnection path between waveguides of the PLCs.

摘要： An apparatus and method are provided for manipulating light beams propagated through PLCs in free space. Light beams propagated in through an input/output waveguide of a PLC are propagated through a waveguide array to generate a phased array output at an edge facet of the PLC. The phased array output at the edge facet is spatially Fourier transformed by a lens in free space, generating a spectrally resolved image at the back focal plane of the lens. The spectrally resolved image is reflected, at least in part, by a reflector device and coupled into a desired waveguide array of a PLC to produce a desired output.
