“…Recently, optical fiber gratings, where periodical refractive-index change is fabricated by ultraviolet ͑uv͒ photon irradiation in the core of an optical fiber made of Gedoped SiO 2 glass, 1 have been expanding their applications to various devices, such as optical filters, 2-6 sensors, 7-10 fiber lasers, [2][3][4]11 dispersion eliminators, 12,13 and so on. Many trials, e.g., development of special fibers with increased Ge concentration and/or codopants, have been made to increase the refractive index change.…”

“…bres [6]. Ball et al [24] subsequently demonstrated an all fibre intra-core grating laser in neodymium doped fibre, using a dye laser pump at 830 nm. Sensing applications have also been addressed by Campbell et al [25] and Morey et al [26].…”

Spatially Modulated Bragg Gratings

“…It is also possible to . produce fiber grating lasers either by splicing the reflection grating to an Er-doped fiber [10] or by writing the grating into other rare-earth-doped fibers [13,14]. Chirped Bragg gratings in optical fibers may provide a tool for dispersion compensation [15,16] or pulse compression [17].…”
