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.

Virtual long-period fiber gratings [PDF]
SPIE Proceedings, 2004 In this paper a theoretical prediction of a new kind of in-fiber devices is presented. They behave essentially like long-period Bragg gratings except for the fact that they are not permanent but volatile. This is because these devices are not formed by the UV-induced increment of the refractive index but by the twisting of a pristine HiBi fiber.

Photonics, 2022 Phase-inserted fiber gratings (PI-FGs) refer to those gratings where there exist a number of the phase-shifts (spatial spacing) among different sections (or local periods) of the gratings themselves. All the PI-FGs developed to date can mainly be divided
