We report a new type of GaAs/AlGaAs electro-optic effect device which offers a built-in optical nonlinearity at extremely low power operation working in the pW to μW regime. The device consists of semitransparent metal electrodes evaporated directly onto the undoped AlGaAs cladding layers of a multiple quantum well structure. We briefly characterize the optical nonlinearity which is based on the quantum-confined Stark effect and discuss the underlying physical mechanism which relies on the suppression of the internal electric fields of the biased sample. The use of such structures is proposed especially for applications as possible low-power and low-cost optical bistable switch.
