Tunable optical dispersion-slope compensation based on a nonlinearly-chirped bragg grating

Techniques and devices for compensating polarization-mode dispersion in an optical signal by using a nonlinearly-chirped Bragg grating in a dual-pass configuration.

Tunable compensation for polarization-mode dispersion using a birefringent nonlinearly-chirped bragg grating in a dual-pass configuration

A nonlinearly chirped fiber grating for achieving tunable dispersion compensation, dispersion slope compensation, polarization mode dispersion, chirp reduction in directly modulated diode lasers, and optical pulse manipulation. A dynamical dispersion compensation mechanism can be implemented in a fiber communication system based on such a nonlinearly chirped fiber grating.
