Abstract

We analyze signal waveform generated by a semiconductor optical amplifier (SOA)-based switch with a delayed-interferometric (DI) configuration by controlling an assist light under gain or transparent wavelength. To take advantage of the rectangular-shape waveform generated by the switch, we investigate and optimize the waveform quality by means of both Q-factor and concordance rate to rectangular-shape of the converted waveform.
