ABSTRACT:
An optical backplane comprises a light source that transmits a light beam through apertures of aligned circuit cards. An optical modulator on each circuit card writes information onto the light beam. An optical demodulator on each circuit card reads information off of the light beam. The optical backplane interconnects integrated circuits of different circuit cards and minimizes misalignment problems and the likelihood of faulty connections between such circuits.
