Summary Tunable optical filters are important elements for next generation’s high-speed communication systems. With the advance to dense wavelength division multiplexing (DWDM) a suitable filter needs both a large tuning range and a narrow bandwidth to manipulate or select a desired wavelength from the band of available channels. Different approaches are used for the development of dynamic optical filters, such as filters based on Fabry-Perot interferometers, micro machined devices, fiber Bragg gratings, ring resonator tunable filters, acousto-optical or electro-optical tunable filters, and volume holograms. The latter offer the important advantage of very high wavelength selectivity.
