Abstract

In order to achieve effective modulation, researchers have studied various doping profiles within silicon modulators, but optimization has so far mainly been carried out in the cross-section or solely in the propagation direction. Generating 3D doping profile can add more optimizing dimensions to the modulator design. This work proposes a modulator based on U-shaped and L-shaped junctions by the 3D effective Monte-Carlo method. The simulation results show that the modulation efficiency is 0.67 V·cm, and the loss is 25.7 dB/cm, with the bandwidth more than 36.3 GHz. This work demonstrates the benefits of 3D modulator design as the direction of light propagation is utilized to transport carriers, and provides a modulator solution for high-speed datacom.
