Abstract

Future networks will use optical techniques to implement control logic as well as transmit data and will employ wavelength division multiplexing to exploit the bandwidth of monomode liber. The following experiment shows that a semiconductor-laser amplifier with Fabry-Perot resonances acts as a bandpass filter, optically tunable by a control signal at a different wavelength. It could, therefore, be used as an optically controlled demultiplexer.
