Use of OPA for switching and routing in WDM networks
2000 (English)Patent (Other (popular science, discussion, etc.))
The present invention is an arrangement for utilizing optical information sent through an optical network from a sending site to at least one receiving site. An optical parametric amplifier OPA receives the optical information sent at a set of input wavelengths. A mixer amplifier mixes the input wavelengths with an optical pump wavelength. A set of optical conjugate copy wavelengths are generated from the set of input wavelengths. A WDM-splitter separates the set of input wavelengths from the set of conjugate copy wavelengths. The set of input wavelengths and/or the set of conjugate copy wavelengths are forwarded individually to the at least one of the receiving site.
