Modeling rare turn-on events of injection lasers

An efficient numerical method based on photon statistics and rate equations is developed to simulate rare turn-on events of injection lasers. Results indicate that: (1) during the transient stage, with a probability of 10/sup -9/, the side-mode suppression ratio can deteriorate by three orders of magnitude from its steady-state value; (2) there is a turn-on jitter for the main mode, even when the side mode is missing; and (3) the slower the risetime of the laser output the less the transient mode partitioning. The effects of gain compression and driving condition on the transient turn on are discussed.>
