  • Dispersion compensation
    Publication number: 20030072532
    Abstract: A dispersion compensation apparatus (10) includes a chirped fibre Bragg grating (CFBG) (12) coupled to a mechanical support (16) within a bending apparatus (14). The bending apparatus (14) is operable to bend the mechanical support (16) and hence the grating (12). Bending the grating (12) changes the periodicity, and thus the group delay characteristic, of the grating. The group delay characteristic of an initially linearly CFBG can thereby be made nonlinear. The grating (12) may be used to simultaneously compensate for chromatic dispersion and dispersion slope, and can therefore be used to recompress optical pulses.
