Abstract
We propose and demonstrate generation of an in-phase optical pulse train from an optical beat signal. The proposed method is based on four-wave mixing occurring between the two continuous waves of the beat signal and on spectral filtering to shape the spectrum to be symmetric about the carrier frequency. We perform an experiment to verify the proposed method and obtain a width in-phase pulse train from a beat signal. Furthermore, we employ a pulse compression scheme to reshape and compress the obtained pulse train, and we show that a repeating, FWHM, nearly transform-limited, in-phase sech pulse train is successfully generated.
