Abstract
Systems and methods for producing ultra-short optical pulses are provided. According to various embodiments, optical pulses are generated, stretched, amplified, and compressed to ultra-short lengths. In order to achieve the ultra-short lengths, dispersion compensation is provided prior to amplification and optionally before compression. Dispersion compensation prior to amplification can be performed by passing the optical pulses through a polarization-maintaining fiber that includes a nonlinear Bragg grating. In some embodiments, the optical pulses are repeatedly circulated through the polarization-maintaining fiber that includes the nonlinear Bragg grating. Dispersion compensation before compression can be achieved by passing the amplified optical pulse through another length of polarization-maintaining fiber.
