Long-wavelength multiple quantum well modulators

Thomas H. Wood

Avariety of novel physical effects have been observed in multiple quantum wells (MQWs), which are thin layers of a low band-gap semiconductor surrounded by higher band gap material. Frequently, quantum mechanical effects are manifested in useful, macroscopic properties. Several years ago, it was discovered that large changes in the zero-point energies of particles in MQWs could be achieved by the application of an electric field perpendicular to the quantum well layers.
