Abstract
A device for processing optical signals comprises sources each delivering, substantially simultaneously, optical signals in accordance with a comb of at least two different wavelengths or a continuum of wavelengths. It further comprises multiplexers adapted to deliver to at least one primary port a multiplex of channels corresponding to chosen bandwidths produced from optical signals received at secondary ports each provided with selective spectral filters adapted to pass optical signals whose wavelengths belong to one of the bandwidths corresponding to one of the channels of the multiplex. It further comprises optical routers for routing the optical signals delivered by the sources to secondary ports of the first multiplexers as a function of instructions received.
