Abstract :
Measurement of the large-signal transient response of a high-speed InGaAsP laser to an ultrashort rise time current pulse is reported. For complete time resolution, a measurement system which uses optical correlation techniques is implemented. Comparison is made between the optical correlation measurement and conventional electronic measurement using the fastest available detector and oscilloscope.
