Abstract :
The dispersion characteristics of hepatised linearly-chirped fibre gratings have been studied systematically. It is shown that the hyperbolic tangent profile results in an overall superior performance, as it provides highly linearised time-delay characteristics with minimum reduction in the linear dispersion. To compensate for the linear dispersion of 100 km of standard telecom fibre over certain bandwidth (in nm), the required grating length is 19.24 cm/nm.
