Abstract

An optical pulse can be compressed by passing it through a single-mode fiber to induce a frequency chirp (as a result of self-phase modulation) followed by compression by a grating pair. This technique has produced pulses as short as 30 fsec (Ref. 1) and high compressions in single and two-stage configurations.² The technique is potentially useful over a wide range of input pulse parameters, but the magnitude of the compression and the quality of the compressed pulse are sensitive functions of the width, peak power, and wavelength of the input pulse as well as depending critically on the fiber length and the separation between the gratings.
