Abstract

We demonstrate electro-optic ultrafast control of the optical quality factor of an on-chip silicon microcavity. The micrometer-sized cavity is formed by light confinement between two microring resonators acting as frequency selective mirrors. The ring resonators are integrated into p-i-n junctions enabling ultrafast injection and extraction of carriers. We show tuning of the cavity quality factor from 20,000 to 6,000 in under 100ps. We demonstrate both high-Q to low-Q and low-Q to high-Q transitions.

Sensitivity of the supermode transmission to changes in the distance between the coupled cavities. A 1% change in the distance between the cavities shows a 30% change in the transmission of the supermode.

(a) Gray curve shows the transmission spectrum when a forward bias is applied to the ring corresponding to lower wavelength resonance. The black curve shows the transmission of the unperturbed device. (b) Time response of the transmission at λ probe as the Q of the device is switched from a low- to a high-Q state. (c) Time response of the transmission at λ probe as the Q of the device is switched from a high- to a low-Q state.
