Near-Nyquist optical pulse generation with fiber optical parametric amplification

Camille Sophie Brès, Mohammad Amin Shoaie

A novel method using optical fiber parametric amplification and phase modulation is proposed in order to generate Nyquist pulses. Using parabolic pulses as a pump, we show theoretically that it is possible to generate Nyquist pulses. Furthermore, we show t ...
