Abstract
An experimental and theoretical study of large-signal switching transients in directly modulated semiconductor lasers shows that the main parameters affecting high-speed switching are the small-signal relaxation oscillation frequency and the optical on/off ratio of the pulses. Simple expressions agree well with measured data and can be used to obtain an estimate of the maximum achievable modulation bit rate.Keywords
