Abstract
Short optical pulses from injection lasers are necessary for ultrahigh-speed optical communications systems. One method by which ultrashort pulses can be generated from injection lasers Is electrical gain switching.1 Gain-switched pulses as short as 11 ps have been reported for an InGaAsP laser.2 However, chirp associated with gain switching may have serious implications in long-haul fiber systems.3 We report measurements of gain switching and associated chirp in high-speed 1.3-μm InGaAsP lasers. In particular, we measure with a temporal resolution of 0.5 ps the central wavelength of the laser emission for pulses of <20-ps duration. The temporal resolution achieved is more than an order of magnitude superior to any previous study of chirp in injection lasers and permits a detailed comparison of experiment and theory.
