Abstract : A distributed feedback optical device using a single crystal boule prepared with periodic spatial striations of ternary Pb(1-x)Sn(x)Te and Yb impurity atoms forming a layered array of planar p-n junctions normal to the axis of light emission. Crystal surfaces parallel to the axis are coated with a reflective, electrical insulator. Free scattering losses are minimized by applying a magnetic field along the longitudinal axis. (Author)
