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...
