摘要

In this paper,we reported an integrated method to generate ultra-wideband(UWB)pulses of different orders based on a reconfigurable silicon micro-ring resonator-coupled Mach-Zehnder interferometer.Under proper operating conditions,the device can produce Fano resonances with a peak-to-valley extinction ratio of above 20 dB.UWB monocycle and doublet signals with picosecond pulse widths are produced when the micro-ring resonator is modulated by square and Gaussian electrical pulses,respectively.With our Fano resonance modulator on silicon photonics,it is promising to foresee versatile on-chip microwave signal generation.
