In this contribution, we will review our recent activities in the development of double nested cavity lasers. Several stable operating regimes can be achieved over a wide range of conditions.
We propose and experimentally demonstrate a reconfigurable photonic RF differentiator based on a Kerr frequency comb generated in an integrated nonlinear microring resonator. The RF magnitude and phase responses are experimentally characterized. Systems demonstrations for Gaussian input signals are also performed.
The recently-introduced use of integrated frequency combs (on-chip light sources with a broad spectrum of evenly-spaced frequency modes, generated by four-wave mixing in optically-excited nonlinear microcavities) below optical parametric oscillation threshold for quantum state generation has provided a solution for scalable and multi-mode quantum sources [1, 2]. Pulsed quantum frequency combs, in...
Using high nonlinear enhancement in a CMOS compatible microring resonator incorporated in a SOA based nonlinear loop-mirror laser architecture, we observe passive mode-locking at extremely-low power levels generating 570ps pulses at a 14.8MHz repetition rate.
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 report an integrated, CMOS-compatible source of multiplexed heralded photons, distributed over several wavelengths at standard communication channels and compatible with quantum memories. Our system operates in a self-locked mode without an external pump laser.
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 demonstrate orthogonally polarized photon pair generation via spontaneous non-degenerate four-wave-mixing (FWM) of orthogonally polarized pumps in a CMOS compatible micro-ring resonator by fully suppressing stimulated FWM. Photon coincidences and optical parametric oscillation are measured.
