Optical beam steering in InGaAsP multiple quantum wells

Abstract

We demonstrate an optical beam steering device in InGaAsP multiple quantum wells. Electrical currents are injected through two parallel electrodes, separated by a 20-µm gap. By varying this current ratio, an optical beam is confined by the waveguide formed by the distribution of carriers, is steered continuously across the gap.
