Abstract : An apparatus for a method for assuring the secure transmission of information between a transmitter and a receiver is fabricated along the lines of a Mach-Zehnder interferometer. Two, identical length single-mode fibers extend between the transmitter and receiver to act as transmission paths. Within the transmitter a coiled length of like single-mode fiber integrally extends from one of the fibers reaching from the transmitter to the receiver. Within the receiver a like length of like singlemode fiber integrally extends from the other end of the other fiber reaching from the transmitter to the receiver. A superradiant diode in the transmitter emits pulses of coherent wavetrains that are split and sent through the two lengths of fibers and their associated integrally connected coils.
