1. A reconfigurable multifunctional optical device comprising:

  • an optical arrangement for receiving a first optical input signal and a second optical input signal, each of the first and second optical input signals having optical bands or channels, the optical arrangement having a free optics configuration with a light dispersion element for spreading each of the first and second optical input signals into respective optical bands or channels on separate portions of a spatial light modulator having an array of micromirrors and being programmable to perform separate optical functions on each of the first and second optical signals;

    the spatial light modulator having a first set of micromirrors programmed to perform a first overall optical function on the first optical input signal, and having a second set of micromirrors programmed to perform a second overall optical function on the second optical input signal, wherein the first overall optical function and second overall optical function are different.
