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.
Claims1
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.
