| Title: | Nearly chirp- and pedestal-free pulse compression in nonlinear fiber Bragg gratings | Authors: | Li, Q Senthilnathan, K Nakkeeran, K Wai, PKA |
Issue Date: | 1-Mar-2009 | Source: | Journal of the Optical Society of America B : optical physics, 1 Mar. 2009, v. 26, no. 3, p. 432-443 | Abstract: | We demonstrate almost chirp- and pedestal-free optical pulse compression in a nonlinear fiber Bragg grating with exponentially decreasing dispersion. The exponential dispersion profile can be well-approximated by a few gratings with different constant dispersions. The required number of sections is proportional to the compression ratio, but inversely proportional to the initial chirp value. We propose a compact pulse compression scheme, which consists of a linear and nonlinear grating, to effectively compress both hyperbolic secant and Gaussian shaped pulses. Nearly transform-limited pulses with a negligibly small pedestal can be achieved. | Keywords: | Compression ratio (machinery) Fiber optic components Fiber optic sensors Laser produced plasmas Laser pulses Pulse compression |
