Abstract

Wavelength division multiplexing (WDM) is capable of tremendously increasing the throughput capacity of fiber transmission lines. It can also be used to build all-optical networks (1). To receive the individual channels, these systems employ WDM receivers, which optically demultiplex the different channels before detecting them with photodetectors. Together with an electronic switch array, such a device could also be used as a fast tunable receiver in an all-optical network (2).
