Abstract

We propose a silicon dual-ring modulator consisting of two serially cascaded rings embedded with p-i-n-i-p junctions driven by one signal, in contrast to a differential signal pair. The simulations for optimizing the design of the phase shifter and the optical response of the both rings are performed. We show that the device performs better than the single ring. The modulator has a higher optical bandwidth, 3-dB modulation bandwidth and bit rate as compared to a single ring. In contrast to a cascaded ring modulator driven by a differential signal pair, it can be driven by a single p-i-n-i-p junction and RF signal. A serially coupled ring resonator has three times the resonance linewidth as compared to a single ring. Furthermore, it can support significantly higher data rates of up to 13 GHz.
