Abstract:
An apparatus for transmitting data between first and second VLSI chips, the apparatus comprising:a transmitter disposed on the first VLSI chip, the transmitter having a first material capable of radiating light of a first wavelength when both a zero voltage potential exists across the first material and when illuminated by light of a second wavelength, the transmitter further having voltage control means for controlling the voltage potential across the first material; a receiver disposed on the second VLSI chip, the receiver having a second material capable of producing a signal in the form of a produced voltage potential or produced current flow when illuminated by light of both the first wavelength and a third wavelength, the receiver further having signal detecting means for detecting the presence of the produced signal; at least one light source optically coupled to the transmitter and receiver for illuminating the first material with light of the second wavelength and for illuminating the second material with light of the third wavelength; and light transmission means for transmitting the light of the first wavelength from the transmitter to the receiver.
