Abstract

Micro-ring resonators in silicon photonic circuits have been widely studied and implemented in systems for biosensing [1], telecommunications [2] and generation of photon pairs for quantum optics experiments [3]. The resonator Q-factor, defined by the roundtrip loss and coupling coefficient, is typically a static property of the device realised in the design stage. In this work a method by which to exert active control over both the resonator Q-factor and resonant wavelengths is presented, allowing modulation of resonance enhanced processes such as Four Wave Mixing (FWM) in devices with much smaller footprint than Mach-Zehnder based designs.
