10.2.1 Introduction to fiber photosensitivity The first demonstration of photosensitivity in optical fibers was in 1978 by Hill et al., who produced a Bragg reftection grating in an ordinary germanium doped
HistoryTheoryTypes of GratingsGrating StructureManufactureApplicationsSee AlsoExternal LinksThe first in-fiber Bragg grating was demonstrated by Ken Hill in 1978. Initially, the gratings were fabricated using a visible laser propagating along the fiber core. In 1989, Gerald Meltz and colleagues demonstrated the much more flexible transverse holographic inscription technique where the laser illumination came from the side of the fiber.
