Abstract:
A high speed data link, comprising:(a) a transmitting arrangement having a transmitter output, said transmitting arrangement including (i) a source of light having a certain wavelength, (ii) a layer of superconductive material through which said light from said source must pass before said light can reach the transmitter output, said superconductive material being switchable between a superconducting state in which said light cannot pass therethrough and a non-superconducting state in which said light can pass therethrough, (iii) an arrangement for switching said superconductive material between its superconducting and non-superconducting states to provide a train of light pulses having said certain wavelength and containing optical data, and (iv) a wavelength changing device optically coupled with said layer of superconductive material for changing the wavelength of said light pulses and providing a train of wavelength changed light pulses containing optical data at the transmitter output; (b) an optical fiber, one end of which optical fiber is optically coupled with said transmitter output, for directing said train of wavelength changed light pulses away from said transmitting arrangement; and (c) a receiving arrangement optically coupled with an opposing end of said optical fiber, said receiving arrangement including (i) an all-optical demultiplexer for dividing said train of wavelength changed light pulses into a series of sub-trains of wavelength changed light pulses, and (ii) a series of optical receivers, each of which optical receivers is designed to detect at least one of said sub-trains of wavelength changed light pulses out of the series of sub-trains of wavelength changed light pulses.
