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 (2pi/mm) and loss (dB/mm) 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.
Highlights
Datacenter infrastructure has been one of the fastest growing areas for IT networking driven by ever-increasing need for a higher and faster number of connections between servers and switches
We make predictions of key optical signal fidelity and model optical modulator in conjunction with industrialists based on a careful analysis of experimental data reported in the literature
Eye diagram is generated at the output of an OOK communication system to measure the performance of the system
