AN OPTICAL HOLOGRAPHIC BACKPLANE INTERCONNECT SYSTEM

An optical holographic backplane interconnect system, capable of high-speed information transmission between optoelectronic transmitter/receiver boards, was demonstrated. Using conjugate pairs of transmission gratings in a folded reflection geometry, a practical method can be achieved of insulating the interconnect system from wavelength variations due to temperature or power fluctuations. The final demonstration unit was developed in a fully packaged form and has the potential for reconfigurable interconnects as well as for serving as a testbed for a variety of interconnect networks and hardware protocols.
