Bias dependence of mode dynamics in a vertical-cavity surface-emitting laser

Results are presented showing the effect of bias current on mode competition in the large-signal modulation response of a vertical-cavity surface-emitting laser. The overshoot and turn-on delay between the LP/sub 01/ and LP/sub 11/ modes are observed to be strongly dependent on the bias current relative to the individual mode threshold currents in both experiments and simulations.
