Experimental demonstration of an all-optical 2R regenerator with adjustable decision threshold and "true" regeneration characteristics

Experimental 2R regeneration characteristics of an Optical Decision Circuit based on a Mach-Zehnder Interferometer with Gain Clamped Semiconductor Opt ical Amplifiers in both arms are reported for the first time. The decision circuit gives a true regeneration, i.e., a digital characteristic on a line ar instead of a logarithmic (or dB) scale for the input and/or output power .
