Abstract

We report transmission performance depending on frequency response of receivers and chirping shape of transmitters for 10 Gb/s LiNbO3 modulator based lightwave systems. By solving the nonlinear Schrodinger equation including developed chirping and extinction ratio (ε) models for transmitters, and frequency response and noises for receivers, we have evaluated transmission performance by bit error rate (BER) and eye opening penalty (EOP). Calculated BER and EOP characteristics are compared to the measured BER characteristics so that we can find which combination between chirping model and frequency response for receivers is the best model to estimate the tendency in sensitivity degradation similar to the measured BER characteristics. The simulation results suggest that calculated BER characteristics using the Bessel-Thomson filter as a receiver frequency response model provide better prediction to estimate system performance. Furthermore, different chirping models may be used for positive and negative chirp parameters for better estimation of BER.
