Abstract :
We report a novel fabrication technique for UV-inscribing chirped fibre gratings of arbitrary Bragg wavelength and intrinsic apodisation profile employing a single chirped phase-mask and a scanning Talbot interferometer set-up. Chirped gratings with bandwidth up to 5 nm have been successfully produced over a large wavelength range. Compared to gratings written by using standard fabrication methods, it has been shown that these gratings exhibit time-delay response of small ripple effect.
