CdS photoelectric device: Modulation and optical bistability at 514 nm

Abstract
We discuss the nonlinear characteristics of hybrid CdS devices at room temperature by using increasing absorption at a wavelength of 514.5 nm. Via the thermo-optical properties, a self-electro-optic effect occurs due to the optically induced dissipation of electrical power. As a special application, the device can be utilized as an electro-optic modulator for Ar+ laser light. In addition, voltage controlled optical bistability is also observed.
