Fabrication of chirped fibre gratings using etched tapers

Fabrication of chirped fibre gratings using etched tapers
Fabrication of chirped fibre gratings using etched tapers
A technique for fabricating fibre gratings with an accurately controlled chirp profile is demonstrated. It involves writing a grating over a section of fibre, the cladding of which has been tapered by etching in HF acid. A strain gradient along the taper is used to produce the chirp either during or after writing. Linearly chirped gratings with bandwidth up to 4.8nm have been demonstrated. Transmission filters have also been demonstrated when a step is made in the taper.

Abstract

A technique for fabricating fibre gratings with an accurately controlled chirp profile is demonstrated. It involves writing a grating over a section of fibre, the cladding of which has been tapered by etching in HF acid. A strain gradient along the taper is used to produce the chirp either during or after writing. Linearly chirped gratings with bandwidth up to 4.8nm have been demonstrated. Transmission filters have also been demonstrated when a step is made in the taper.
