ABSTRACT:
The present invention provides an all optical system for correcting optical dispersions including at least one optical chopping device having an input terminal for receiving a first signal, which has been broadened by optical dispersions and corresponds to an optical information channel, and at least one output terminal, wherein the optical chopping device is arranged to produce in the at least one output a second signal that is narrower than the first signal. The second signal may be detectable more reliably than the first signal.
