Abstract

Normalized laser rate equations suitable for large signal analyses are discussed. A large signal laser model suitable for system level simulations is presented. Predicted laser modulation response characteristics are given for Fabry-Perot lasers and compared to measured results. The dependence of the laser modulation response on the laser relaxation-oscillation peak frequency and laser biasing is predicted and compared to measured values. It is demonstrated that the small-signal carrier modulation bandwidth is limited mainly by the intensity dependence of the modulation frequency and the laser's damping rate of oscillation. Simulated and measured results demonstrate that the relaxation-oscillation peak frequency is a reasonable estimate for the modulation bandwidth, and the variation of the modulation response with the output power is nearly flat at fixed modulation frequencies.
