Optical Signal Processing Devices

Abstract

In the previous chapters we have presented advanced optoelectronic devices which performed a specific task: generation of coherent radiation, modulation, light detection or multi/demultiplexing. In this chapter the perspective is reversed. Namely, we will show that with a few devices one can process a light pulse, i.e. one can change its duration, its shape, one can divide it, memorize it, perform logic operations with it or even obtain experimentally integral transforms of it.
