Abstract

We discus an all-optical flip-flop memory and a wavelength converter based on nonlinear polarization rotation in a semiconductor optical amplifier. The flip-flop is realized from two coupled polarization switches. The concept is explained and experimental results are presented that demonstrate that a contrast ratio of over 20 dB and a switching power of less than -3 dBm can be obtained. The all-optical wavelength converter employs a single polarization switch. We show that error-free inverted and non-inverted wavelength conversion can be realized at a data-rate of 10 Gbit/s. Both optical signal-processing functionalities can be utilized in all-optical packet switches.
