Abstract

There is currently considerable interest in wavelength division multiplexed (WDM) systems. In telecommunications, this ranges from full exploitation of the fiber bandwidth in very high bit rate links, through service segregation, to supplying customers in the local loop on different wavelengths (see Fig. 1).¹ Sophisticated wavelength routing architectures are also being studies. Also, in computing it is now recognized that the numerous connections required between processors is imposing serious electronic bottleneck problems. Optical interconnects are offered as the solution² and, again, full utilization occurs with the use of multiple wavelengths.
