Reed2, Azita Emami1 California Institute of Technology, Pasadena, CA University of Southampton, Southampton, United Kingdom 1 2 Data centers continue to require interconnects with higher bandwidth densities and energy efficiencies. Silicon photonics (SiP)-based solutions have gained interest for implementing low-cost and power efficient 100+Gb/s/λ optical transceivers. While microring modulators (MRMs) have small footprints and high electro-optical bandwidth (EOBW), they suffer from an inherent tradeoff between bandwidth and optical phase efficiency, high sensitivity to process and temperature variations, and non-linear electrooptic characteristics [1-2]. Travelling-wave Mach-Zehnder Modulators (TW-MZMs) require power-hungry drivers to compensate microwave losses and occupy large areas on chip [3-4]. Metal-oxide-silicon-capacitor (MOSCAP)-based phase modulators can
