Optimized Design of Inductive-peaking Si Microring Modulator for Operating Bandwidth over 65 GHz

Abstract

We design a high-speed inductive-peaking Si microring modulator integrated with an on-chip spiral inductor to extend the 3dB operating bandwidth beyond 65GHz and increase the conversion gain by 5 dB. A 64Gb/s transmission is demonstrated.

Study of Electrical and Optical Peaking of Si Ring Modulators for Tailoring Modulation Band

“…Previously, we have demonstrated a Si MRM with an operating bandwidth over 65 GHz via the inductive peaking scheme [27]. In this paper, we comprehensively study the EO conversion response of a Si MRM based on the transfer function of an equivalent circuit model according to the MRM structure and operating condition.…”
