Abstract

An all-optical memory with three states is presented. The optical memory is realized from three-coupled identical nonlinear polarization switches. 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 concept is explained and experimental results are presented that demonstrate that a contrast ratio of over 20 dB and a switching power of around 8 dBm can be obtained. This concept can be extended for an all-optical memory with a large number of states, which is crucial to realize 1×N all-optical packet switches.
