Silicon photonics enables new pinnacles of large-scale photonic integration, aiming at the need for large bandwidth in next-generation data centers and interconnects systems. Ultra-high data streams are thus required in the smallest footprint using the lowest amount of power possible. On the silicon-on-insulator platform, microring modulators are a promising solution providing desirable compactness...
Ultra-high data rate is required for future cloud computing and interconnects systems, for which integrated optical transceivers provide promising solutions. We report 66 Gb/s, on-off keying (OOK) operation of a silicon microring modulator (MRM) consuming a low power of 15 fJ/bit. To the best of our knowledge, this result features the fastest binary shift keying operation using a MRM.
We propose an analytical, time-domain model for microring modulators, which encompasses pn-junction and resonator dynamics. It shows excellent agreement with experiment for high frequency operation beyond 20 GHz. Pulse-amplitude modulation is predicted for up to 80 Gb/s.
