Abstract
An optical wavelength switching system utilizes wavelength selective splitters and combiners arranged in one or more stages to select one or more wavelengths for optical switching. In an embodiment, the splitters and the combiners comprise tunable optical filters which are capable of being tuned to selected wavelengths for optical switching in a dense wavelength division multiplexing (DWDM) network.
