Abstract
Generation and application of chirp optical pulses is described. Chirp optical pulses are thelight of which instantaneous frequency are widely swept in several terahertz range within thedurations of picosecond to subpicosecond pulses. Chirp pulses are generated by using groupdelay dispersion with femtosecond pulses, nonlinear spectral broadning in an optical fiber, electrooptic modulation, and so on. With the use of the chirp optical pulses, it is possible notonly to generate ultrashort pulses but also to shape the otical pulses in femtosecond resolution. Electrooptic methods are emphasized to generate and to control the chirp pulses in this paper.
