D. A. B. Miller, "Quantum Well Electroabsorptive Devices: Physics and Applications," in "Optical Computing, ed. B. S. Wherrett and F. A. P. Tooley, Proceedings of the 34th Scottish Universities Summer School in Physics, Edinburgh, August 1988 (Scottish Universities Summer School in Physics, Edinburgh, 1989; Adam Hilger, Bristol, 1989) pp 71-94.

Quantum wells are one of the more promising developments for applications in optical devices. They offer low-energy optical mechanisms compatible with laser diode light sources and semiconductor electronic devices and are particularly well suited to integration with electronics and for fabrication of two-dimensionally parallel arrays compatible with the opportunities of free-space optics. A brief summary of quantum wells, their electroabsorptive properties and their possible applications in optical switching and computing is given. The author introduces layered semiconductor structures and quantum wells and proceeds to summarize electroabsorption in semiconductors in general and in quantum wells, introducing in particular the quantum-confined Stark effect (QCSE). Optical modulators are discussed and the self-electro optic-effect devices (SEEDs), are summarized
