An optical memoryÄ10Ü having an input portÄ12Ü for receiving an input optical signal to be stored in the optical memory is disclosed. A portion of the optical signal is coupled to a storage loopÄ13Ü for storing optical signals by a coupler that transfers a portion of the input optical signal to the storage loop. An optical signal stored in the storage loop is output by coupling a portion of that optical signal to a first external optical waveguideÄ17Ü. The storage loop includes a semiconductor optical amplifierÄ 15Ü for amplifying the signals stored in the storage loop to compensate for losses incurred by those signals in traversing the storage loop. A plurality of such optical memoriesÄ301, 302, 303Ü can be combined to form a larger memoryÄ300Ü that includes a reconditioning circuitÄ310Ü that resets the amplitude of the optical signals to a value that depends on the amplitude of the optical signals. <IMAGE>
