Long-period gratings in chalcogenide fibers
Optics Express, 2006 We report the first demonstration of long period gratings in single mode As(2)Se(3) chalcogenide glass fiber. The grating is implemented by pressing a threaded rod against a short piece of fiber. Its strength can be tuned over a 25 dB range, has high repeatability, and is fully reversible.

Long Period Gratings Formed in Depressed Cladding Fibres [PDF]
Bragg Gratings, Photosensitivity, and Poling in Glass Fibers and Waveguides: Applications and Fundamentals, 1997 There has been a significant interest in long period gratings, primarily due to their applications in gain-flattened erbium doped fibre amplifiers [1]. Up till now, cladding modes supported by the glass-air interface of an optical fibre have been used in a forward mode coupling scheme involving also the guided fundamental mode of the optical fibre ...

Modification of the refractive index response of long period gratings using thin film overlays. [PDF]
, 2005 The response of a fibre optic long period grating (LPG) to the surrounding refractive index is shown to be modified by the deposition of a thin film of thickness of order 100 nm onto the cladding.

Long Period Fibre Gratings [PDF]
, 2012 In essence, a long period fibre grating (LPFG) is an all-fibre device with wavelength dependent loss. As a band rejection filter, all light in a spectral slice is discarded without affecting the amplitude and phase of neighbouring wavelengths, with the additional advantage of low insertion losses and minimum backreflection (Daxhelet, 2003).

Photochemical long-period grating fabrication in pure-fused-silica photonic crystal fiber [PDF]
, 2007 We report on first photochemical recording of a long-period fiber grating (LPFG) in a pure fused silica photonic crystal fiber (PCF), which is based on two-photon absorption (TPA) of high-intensity femtosecond 264 nm pulses.
