Abstract

We demonstrate bandwidth enhancement of external- and direct-modulated lasers using a tunable optical equalizer. Modulation bandwidth of >50 GHz for LiNbO₃ modulators was obtained. Also, the equalizer permits the increased-speed and chirp-reduction simultaneously for direct-modulated VCSELs.
