Abstract
An optoelectronic packet switch comprising: switch input(s) for receiving optical packet signals; a passive optical router; a control unit; and a plurality of detector-remodulators (DRMs) configured to receive signals from the switch input(s) and to generate modulated optical signals for transmission to the input ports of the passive optical router. Each DRM comprising: detector(s) for converting an optical packet-signal received at the switch input(s) into an electrical packet-signal; modulator(s) for generating the modulated optical signals. Each modulator configured to: receive a wavelength-tuned input from a tunable laser; receive the electrical packet-signal from one of the detectors; and to generate a modulated optical signal at the tuned wavelength, the modulated signal containing the information of the electric packet-signal and the tuned wavelength chosen to select an output port of the passive optical router for the modulated optical signal; and an electronic circuit connecting each of the detector(s) to a corresponding modulator.
