Tunable mechanically induced long-period fiber gratings

Optics Letters, 2000
We report the experimental characterization of mechanically induced long-period fiber gratings (LPFG's) made by pressing a plate with periodic grooves against a short length of fiber. This filter, which is simple and inexpensive, exhibits transmission spectra and temperature stability similar to those of photoinduced LPFG's.

Progress in long period fiber gratings

Conference Proceedings. LEOS'98. 11th Annual Meeting. IEEE Lasers and Electro-Optics Society 1998 Annual Meeting (Cat. No.98CH36243), 2002
Summary form only given. Long period fiber gratings have been used in a variety of applications such as gain equalization filters for optical amplifiers, band rejection filters and sensors for temperature and strain. Among these applications, gain equalization is the most demanding and interesting because of the impact of broadband gain-flattened EDFA ...

Refractive index sensitivity in thinned long period gratings

SPIE Proceedings, 2007
In this work, we report the exptl. investigation of the sensitivity characteristics to the surrounding refractive index (SRI) in thinned long period gratings for a wide range of fiber diams. and different low orders cladding modes. Wet chem. etching combined with microscopic anal. allow us to identify the exptl. dependence of the SRI sensitivity on the
