Burst-mode operation of a 650GHz mode locked laser based on a high order microring resonator

We demonstrated a new regime of operation for ultrafast mode-locked lasers that we termed “burst-mode” modelocking. By exploiting an integrated 11
^th
order micro-ring resonator, our scheme achieves stable operation resulting in a mode-locked train of pulses at 650 GHz with a burst mode envelope of 40 ps at 7.12 MHz.
