Abstract
A switch device and method is disclosed that is capable of switching wavelength division multiplexed optical signals. The device comprises a switch element, which may include a detector, an emitter array, and a switch controller. The detector is adapted to detect optical signals and is positioned to receive light from a source. The emitter array is positioned to transmit light to a plurality of targets. The emitter comprises at least one emitter and a modulator array. The modulator array selectively allows light to pass through the modulator array. The switch controller is in communication with the detector and the emitter array. The switch controller is adapted to cause the emitter array to generate the detected signal. The switch elements are grouped in an array and dichroic beam splitters may be used to reflect predetermined ranges of wavelengths to the individual switch elements.
