We demonstrate the modulation of silicon ring resonators at RF carrier frequencies higher than the resonance linewidth by coupling adjacent free-spectral-range (FSR) resonance modes. In this modulator scheme, the modulation frequency is matched to the FSR frequency. As an example, we demonstrate a 20 GHz modulation in a silicon ring with a resonance linewidth of only 11.7 GHz. We show theoretically that this modulator scheme has lower power consumption compared to a standard silicon ring modulator at high carrier frequencies. These results could enable future on-chip high-frequency analog communication and photonic signal processing on a silicon photonics platform.

  14. Based on our analysis for the FSRC modulator, the RF wavelength is about eight times of the half electrode length (since the electrode is fed at the midpoint of the electrode) at the FSR frequency considered in this work. Therefore, a lumped model is a valid approximation.
