Abstract
Error-rate measurements have been performed on an experimental all-optical regenerator at 140 Mbit s−1 for a range of input wavelengths in the 1.5-μm band. The best sensitivity was −40 dB m and the maximum gain 31.5 dB from facet to facet. Wavelength translations from −11 to +24 nm were obtained for a penalty of less than 5 dB. The regenerator used the interaction of the input signal with an optical clock waveform in a bistable laser amplifier to re-time the signal and restore the data levels. Future applications may include use in a repeater, as an interface in a wavelength-multiplexed network or as a logic element.
