We demonstrated the generation of Nyquist pulses using a dual parallel Mach-Zehnder modulator. 10 GHz to 40 GHz Nyquist pulses with timing-jitter below 258 fs and signal-to-noise ratio more than 30 dB are experimentally generated.
We demonstrate a method to realize arbitrary repetition-rate multiplication of 40 GHz optical pulses based on optical spectrum manipulation. The generated 80–320 GHz pulses can well maintain the original pulse shape with uniform amplitude and improved SNR.
