VCSEL Based Optoelectronic Oscillator (VBO) for 1.25 Gbit/s RZ Pulse Optical Data Generation

We present the implementation results of a VCSEL based optoelectronic oscillator (VBO) in terms of phase noise and time jitter in the electrical and optical domain. The electrical signal at 1.25 GHz is used as a clock for Non-Return-to-Zero (NRZ) data generation. A system for optical pulse data generation to obtain duty cycles (DC) lower than 30% is proposed and simulated.
