摘要：An all-optical flip-flop device is achieved by employing two optical amplifiersarranged so that they together operate in only one of two stable states at a given time.In a first stable state of operation, the first optical amplifier behaves as a laser having afirst predetermined characteristic wavelength. The arrangement is switched to a secondstable state of operation in which the second optical amplifier behaves as a laser having asecond characteristic wavelength, where the first and second characteristic wavelengthsare at least nominally different, when an optical signal pulse is received at the input ofthe first optical amplifier. The arrangement is switched back to the first stable state whenan optical signal pulse is received at the input of the second optical amplifier.
