A new dynamic equivalent circuit model for vertical‐cavity surface‐emitting lasers (VCSEL) is developed to add to the equivalent circuit model family of lasers. To describe the laser dynamics, the microcavity model is coupled to the rate equations. The relationship between photon number and standing wave in the cavity is derived for the coupling. A spontaneous emission noise source is applied to the circuit to simulate the noise process throughout the laser operation. Simulation results show that the model is accurate and effective to provide the modulation response of optical wave, carrier and photon populations, frequency chirping, and output power. ©1999 John Wiley & Sons, Inc.
