Multi-user System Simulation for a Fully Integrated 40Gb/s Mode-Locked Laser Source/OCDMA Encoder

4x40 Gb/s Optical-CDMA encoding/decoding is numerically demonstrated using a monolithic mode-locked laser source/encoder and nonlinear detection in a multi-user environment. Each user achieves a 10 dB extinction-ratio after decoding to demonstrate feasibility for optical data-communications.
