"The rapidly developing fields of optical communications and optical computing have stimulated extensive research toward integrated optoelectronic devices. One of the most promising developments to come out of this effort was the invention of a new class of "man-made" materials called multiple quantum wells (MQW's). These multi-layered structures exhibit improved performance in electrooptical as well as all-optical switching functions and offer a great potential for future device applications. However, since the market for these devices still relies heavily on conventional electronic components, the application of optical systems under electronic control seems much more near term. This report therefore concentrates on the electric-field dependent switching in a non-linear MQW directional coupler"--Abstract, page iii. Directional couplers. Optoelectronics. Quantum wells.
