bstract-We discuss an all-optical wavelength converter based on nonlinear polarization rotation in a single semiconductor optical amplifier.We show that inverted and noninverted wavelength conversion can be realized. We also demonstrate this wavelengthconversion concept can operate over a large wavelength range. Experiments show that error-free wavelength conversion can be obtained at a bit rate of 10 Gb/s.

An all-optical memory with three states is presented. The memory is realized from three coupled ring lasers. The state of the optical memory is determined by the wavelength of the memory's output light. In each state, only one wavelength is dominant. The three-state all-optical memory can be utilized in all-optical packet switches. The concept of the memory is explained and experimental results are presented that demonstrate that a contrast ratio larger than 40 dB between output states of the memory can be obtained.

We demonstrate error-free wavelength conversion at 320 Gb/s by employing a semiconductor optical amplifier that fully recovers in 56 ps. Error-free operation is achieved without using forward error correction technology. We employ optical filtering to select the blue sideband of the spectrum of the probe light, to utilize fast chirp dynamics introduced by the amplifier, and to overcome the slow gain recovery. This leads to an effective recovery ime of less than 1.8 ps for the wavelength converter. The wavelength converter has a simple configuration and is implemented by using fiber-pigtailed components. The concept allows photonic integration.

ptica: flip-flop mcmory with scparalc scl and rcsct inputs is prcsntde. The flip-flop is realised from two coupted pokrisftion swicches. The comcept is explained and experimenal rcsults are pcesented that demonstrale that 2 contrast ratio of 20 dB and a switching power of <-3 dl3: n can be oblained. The all-optieal flip-flop can be utilised in all-optical packct swjtches.
