Optical Processing
First Claim
1. An optical processor having a reflective SLM, a dispersion device and a focusing device, wherein the SLM has a two-dimensional array of controllable elements, wherein the SLM is configured such that each controllable element is selectable whereby two-dimensional groups of controllable elements are formed at chosen locations of the SLM;
- wherein the processor is configured such that, using the focusing device, light from a common point on the dispersion device is spatially distributed by wavelength across at least one of the two-dimensional groups, and wherein the processor is configured such that each of the two-dimensional groups of controllable elements displays a different hologram at the chosen locations of the SLM where said light is incident, for processing said light.

Abstract
A modular routing node includes a single input port and a plurality of output ports. The modular routing node is arranged to produce a plurality of different deflections and uses small adjustments to compensate for wavelength differences and alignment tolerances in an optical system. An optical device is arranged to receive a multiplex of many optical signals at different wavelengths, to separate the optical signals into at least two groups, and to process at least one of the groups adaptively.
