Abstract

Physical Optics Corporation (POC) proposes a new type of highly reconfigurable optical interconnects. This will be accomplished as a hybridization of intergrated planar holo-graphic interconnects and fast addressing, based either on acousto-optic modulators or smectic-A liquid crystals. The basic novelty of POC's approach is in using permanent holograms instead of dynamic holograms (which are slow, expensive and exhibit low efficiency) but in which the reconfigurability is shifted to an electro-optic (or magneto-optic) addressing system. Thus, POC's approach can combine the superior interconnect-ability ruggedness, compactness, and efficiency of permanent planar Bragg holograms with the ruggedness and nanosecond responses time of the fastest optoelectronic addressing systems. POC's reconfigurable holographic interconnects will have the following superior features: A) High interconnectability and parallelity ( > 104-fan-out) B) Compactness, micro-electronic packaging compatibility C) Highly rugged, environmentally and mechanically stable D) Low insertion loss ( < 1db/channel) and low cross-talk ( < -20db), with diffraction efficiency up to 99% E) Fast accessing-switching time ( < lnsec., for acousto-optic modulators (AOMs) and, <20nsec, for smectic-A liquid crystals (LCs)) F) High throughput ( > 1011 channels/sec.) G) Low cost H) Flexible interconnect topology While the properties (A,B,C,D,E) are considered to be necessary conditions for the majority of real-time computing applications, the current state-of-the-art optical interconnects can never satisfy more than two of these requirements. Thus, the proposed interconnects go far beyond the state-of-the-art.
