Turn-On Delay Time Jitter Measurement in Semiconductor Lasers

The problem of evaluating statistical time properties and, in particular, the variance of the turn-on delay time in semiconductor lasers is presented. The results of GaAs diode laser time jitter measurement, as a part of a time-of-flight measurement system with a single-shot resolution of 40 ps, are presented. The results indicate that at fast injection currents, in excess of twice the laser threshold current, the laser turn-on delay time is above 1 ns and with jitter less than 40 ps giving minimum influence on the timing resolution of the measurement system.
