We report on the novel all-optical generation of duobinary (DB) and alternate-mark-inversion (AMI) modulation formats at 42.6 Gb/s from an input on-off keyed signal. The modulation converter consists of two semiconductor optical amplifier (SOA)-based Mach-Zehnder interferometer gates. A detailed SOA model numerically confirms the operational principles and experimental data shows successful AMI and DB conversion at 42.6 Gb/s. We also predict that the operational bandwidth can be extended beyond…

TLDR
It is shown that the minimum bit pattern length scales linearly with the bitrate and the recovery time of the SOA, and the periodic method also simultaneously provides such figures of merit as output power and pulsewidth.
