This invention relates to lasers and more particularly to mirrorless, distributed-feedback lasers. This document describes an apparatus and method for producing distributed feedback in a laser. Electrodes, formed on opposite sides of a waveguide cavity, form a spatially periodic electric field in an amplification medium which exhibits the Stark effect. The field induces a modulation in the laser gain function of the medium which produces laser feedback.
