Abstract

This work describes the theory, design, and experimental results of a generic multipurpose device that can operate as a tunable wavelength filter, wavelength multiplexer and wavelength router. This device could be especially useful in optical networks applications based in both Coarse and Dense Wavelength Division Multiplexing technology (CWDM/DWDM). The enabling component is a Ferro-electric Liquid Crystal (FLC) Spatial Light Modulator (SLM) where dynamic holograms are implemented in real time. As a consequence, the device will be able to carry out different functions according to the hologram recorded on the SLM. The great advantage of this device is a polarization insensitivity operation, allowing low cross-talk and simple handling. Also some topics on Computer Generated Holograms (CGHs) design process are commented and general guidelines also are done. Laboratory experiments have demonstrated the capability of a phase FLC-SLM, with the great advantage of a polarization insensitivity operation, to diffract the incident light according its wavelength and hologram patterns, for the use in the former applications.
