ABSTRACT We demonstrate the performance of a semiconductor photorefractive p‐i‐n diode operating at 1.55 μm in the longitudinal quantum‐confined Stark geometry. The device structure consists of a semi‐insulating InP–GaInAs(P) multiple quantum well, sandwiched between two trapping regions, and embedded in a p‐n junction. In this structure, the measured output diffraction efficiency reaches 0.6%. This value is close to the output diffraction efficiency value estimated from electroabsorption measurements. © 1996 American Institute of Physics.

    ABSTRACT: Describes various techniques to implement optical dynamic interconnections using the photorefractive effect. Two categories of optical dynamic interconnections are discussed. One is based on free-space optics and the other on guided optics. These include a real-time volume hologram, a mutually pumped phase conjugator, a spatial light modulator, a waveguide, and a spatial soliton

    ABSTRACT: Coded ultrafast optical pulses can be treated as one-dimensional (1-D) images in the time domain. We have converted spare-domain images into time-domain images using diffraction from dynamic holograms inside a Fourier pulse shaper, with photorefractive quantum wells (QW's) used as the dynamic holographic medium. We present several examples, in which amplitude or phase modulation of the hologram writing beams modifies the complex spectrum of the femtosecond output, resulting in a time-domain image. Both storage and processing of time-domain images can be achieved, depending on the hologram writing geometry and power densities. Time-domain processing operations such as edge enhancement, Fourier transform, and correlation are demonstrated
