Integrated Quantum Well Switching Devices
Over the past several years, quantum wells have shown themselves to be an important and exciting model system for investigating the physics and applications of quantum confinement for optical switching systems.1-4 Much of this interest is stimulated by the fact that there is an impressive fabrication technology available to make such structures. Together with the interesting physical properties shown by quantum wells, this technology has enabled us to make a variety of novel but relatively practical devices that offer us new opportunities in optical switching. Here I will summarize briefly some of the more recent optoelectronic devices using quantum wells that are based on the unusual electroabsorptive effects in quantum well systems. As we proceed towards more practical devices however, it becomes increasingly important to consider devices in the context of systems, and this consideration is now strongly influencing the directions of work in integrated quantum well switching devices. For this reason, I will start by briefly summarizing some of the more important systems requirements on devices.
