We demonstrate a high-efficiency PAM4 silicon photonics transmitter optimized through end-to-end system modeling for applications up to 10km on four-channel CWDM4 grid. Our measurements show a close agreement with simulations meeting 400G-FR4 require

A frequency-dependent nonlinear model has been proposed and experimentally verified at 100 Gb/s using PAM4. This universal model simply requires adjusting two sets of polynomials based on the THD data and is modulation format agnostic.

Phase-change media [1] in DVD-RAM systems has been a hot bed of research in the past several years. In phase-change optical recording a high power "write" beam irradiates the disk and forms an amorphous mark. The amorphous mark is written in a crysta
