D. S. Chemla, I. Bar-Joseph, C. Klingshirn, D. A. B. Miller, J. M. Kuo, and T. Y. Chang, "Optical Reading of Field-Effect Transistors by Phase-Space Absorption Quenching in a Single InGaAs Quantum Well Conducting Channel," Appl. Phys. Lett. 50, 585-587, (1987).

The authors present the first observation of absorption quenching by electrical control of the carrier density in a single semiconductor quantum well used as conducting channel in a field-effect transistor. The effect is large enough to allow direct reading of the transistor logic state
