In this talk, the physics of microring resonators is discussed in the classical and quantum regimes, in the context of the exploitation of chi-3 effects in these cavities as done by our group. Through the implementation of a novel microring pumping scheme and a quantum reinterpretation of the frequency comb, we present an integrated platform for the generation of quantum optical states spread over...
We demonstrated a new regime of operation for ultrafast mode-locked lasers that we termed “burst-mode” modelocking. By exploiting an integrated 11th 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.
We experimentally demonstrate a new SOI based optical filter design comprising of a photonic crystal cavity and a low index bus waveguide and realise high extinction ratios and low insertion losses.
