Silicon optical modulator simulation

Abstract

We developed a way of predicting and analyzing high speed optical modulator. Our research adopted a bottom-up approach to consider high-speed optical links using an eye diagram. Our method leverages on modular "mapping" of electrical characteristics to optical characteristics, while attaining the required accuracy necessary for device footprint approaching sub-micron scales where electrical data distribution varies drastically. We calculate for the bias dependent phase shift and loss for the optical modulator based on the real and imaginary part of complex effective indices. Subsequently, combine effectively both the electrical and optical profiles to construct the optical eye diagram which is the essential gist of signal integrity of such devices.

Photonics Rib Waveguide Dimension Dependent Charge Distribution and Loss Characterization

“…With high refractive index, light modulation can take place at a faster speed with low consumption of power in silicon waveguide (Liu et al, 2007). Modulation scheme of waveguide can be categorized into three types; carrier injection, depletion and accumulation based electro-optic modulator on silicon-on-insulator (Debnath et al, 2018;Lim et al, 2015;Mulyanti et al, 2014;Qin et al, 2016). In here, carrier injection is chosen to carry out the simulation of charge distribution and the loss characteristics of rib waveguide.…”
