Abstract
A compact silicon ring resonator is demonstrated that allows simple electrical tuning of the ring coupling coefficient and Q-factor and therefore the resonant enhancement of on-chip non-linear optical processes. Fabrication induced variation in designed coupling fraction, crucial in the resonator performance, can be overcome using this post-fabrication trimming technique. Tuning of the micro-ring resonator across the critical coupling point is demonstrated, exhibiting a Q-factor tunable between 9000 and 96000. Consequently, resonantly enhanced Four Wave Mixing shows tunable efficiency between
