New fabrication technique of fibre Bragg gratings with arbitrary chirp and wavelength for chromatic dispersion compensation

Abstract

We present here a new method allowing the fabrication of long gratings with any kincl of chirp at any ivavelength in a range of about 30 nmfor chrurnatic dispersion compensation.

Chirped fiber Bragg gratings for WDM chromatic dispersion compensation in multispan 10-Gb/s transmission

“…Two sets of five gratings were fabricated at 1549.3 and at 1559 nm at Alcatel using the method of telecsopic scanning described in [12]. This method is simple, inexpensive and versatile, allows the inscription of gratings with arbitrary chirp and center wavelength using a single unchirped phase mask.…”
