Measurement of laser parameters for simulation of high-speed fiberoptic systems

The semiconductor laser rate equations are rewritten using a new set of parameters which can all be found from steady state and small signal measurements on the laser. Procedures for finding these parameters are described. Parameters have been measured on three 1550 mm lasers from different manufacturers. Comparison between large signal measurements and simulations using the measured parameters shows in general good agreement for modulation currents sufficiently above threshold.
