ABSTRACT AN OPTICALLY CONTROLLED SELECTOR An optically controlled selector comprises an optical coupler (1) having a first input (2) for an optical input signal, a second input (3) for an optical control signal and an output (4) for a combined signal, and a resonant cavity (5) downstream of the output of the coupler (1) and arranged to receive the combined signal. The resonant cavity (5) contains an optically non-linear material so that changes in the power of the optical control signal result in changes in the resonant frequency of the cavity (5). In use, the power of the optical control signal controls the transmission or suppression of the optical input signal through the optical cavity. Such a selector acts as a simple switch or to select one from a number of optical signals of different wavelength. Preferably the optical material is active and the optical cavity (5) formed by a semiconductor laser amplifier.
