An all-optical flip-flop device is achieved by employing two optical amplifiers arranged 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 a first predetermined characteristic wavelength. The arrangement is switched to a second stable state of operation in which the second optical amplifier behaves as a laser having a second characteristic wavelength, where the first and second characteristic wavelengths are at least nominally different, when an optical signal pulse is received at the input of the first optical amplifier. The arrangement is switched back to the first stable state when an optical signal pulse is received at the input of the second optical amplifier.
