1. A system for parallel transmission of a two-dimensional image through a single mode optical fiber, comprising:

  • a broadband light source;

    a first thin film channel waveguide for dispersing said broadband light into a two-dimensional array of spectral components;

    a two-dimensional spatial light modulator for modulating the intensity of said spectral components of said two-dimensional array to correspond to the two-dimensional image;

    a second thin film channel waveguide for collecting and recombining said modulated spectral components into a broadband light beam;

    a single mode optical fiber connected to said recombining means for transmitting said broadband light beam; and

    a third thin film channel waveguide connected to said single mode fiber for receiving and dispersing said transmitted broadband light beam into said intensity modulated two-dimensional array of spectral components to reproduce the two-dimensional image.
