Paper Abstract

The reflectivity and the Bragg wavelength of a fiber Bragg grating formed in a photonic crystal fiber with central pure core defect and a regular hexagonal array of microscopical holes cladding were investigated by the improved effective index method, the calculated results indicate that the scalar approximation condition will not be satisfied when the filling factor is more than 0.45, the reflectivity increases from 86.6% to 93.9% with the filling factor increasing, and the Bragg wavelength decreases from 1550.347nm to 1549.236nm when f <0.53. This rules provided the theoretical basis for designing new fiber Bragg gratings formed in the PCF.
