All-electric laser beam control by quantum-confined Stark effect modulator with an integrated Bragg grating

Fast all-electric modulation of optical characteristics (effective refractive index, absorption coefficient) of quantum-dimensional semiconductor waveguide heterostructures was studied. These studies are aimed at developing a laser beam spatial characteristics control system using a high-order Bragg grating that is integrally formed on a semiconductor heterostructure. The implementation of this study will provide an ultrafast (nanoseconds) sweep of the laser beam.
