Pulse Compression of 100 Picosecond Pulses at 1.319 Microns
Abstract
A facility providing temporally short pulses is extremely useful for investigating the limitations of optical detectors, or signal processing networks. For instance, two picosecond (ps) pulses have a 500 GHz bandwidth and can therefore be used in experimental systems designed for operation one to two orders of magnitude faster than those presently in use. This report describes the fiber-grating pair optical pulse compression set-up which compresses 110-120 picosecond pulses, with a 1.319 micron wavelength, down to 1-2 ps. The exact temporal width of these pulses is measured by an autocorrelator. It is easy to compress pulses with a wavelength < 1.32 micron if they have the following qualities a) their spectral bandwidth is larger than the inverse of their temporal pulse width and b) the instantaneous frequency varies linearly across the pulse (i.e. it has a linear chirp). In a fiber-grating pair compression stage the light pulse is first coupled into a fiber.
