Abstract :
Laser diode rate-equation parameters are extracted for simulation of on-off keyed digital communication links with below-threshold laser prebiases. The extraction procedure uses measurements of the current-voltage-light characteristic, the ac small-signal response above threshold, and the turn-on delay due to an isolated pulse. Characteristics of the extracted models are discussed in detail. The predictive capability of the extracted models is demonstrated by good agreement between modeled and measured transient response pulse shapes for a prebias current of 0.3 times the threshold current
