Abstract : This paper proposes the use of a two-dimensional planar optical waveguide as a broadcast medium in a semiconductor-wafer scale optical interconnection network. The use of a 2-D guide as a substitute for a conventional star coupler is seen to eliminate the need for optical fiber or integrated optical waveguides together with all precision alignments between the waveguides, sources, and detectors. Received optical power is shown to scale inversely with the number of stations in the network, just as for the case of the star-coupler-based network, with an additional network-size-independent loss of at most 13 dB. The proposed scheme is capable of providing a 7 Mb/s interconnection channel for each pair of elements in a 256-element planar array of electronic circuits.
