Bragg gratings in air–silica structured fibers
Optics Letters, 2003We report on grating writing in air-silica structured optical fibers with pure silica cores by use of two-photon absorption at 193 nm. A decrease in propagation loss with irradiation was observed. The characteristic growth curves were obtained.

Ultrashort bragg soliton in a fiber bragg grating
Optics Communications, 2002The propagation of a nonlinear ultrashort pulse in a photonic bandgap structure is investigated by using the finite-difference time-domain method. The simulation results show that an ultrashort pulse near the bandgap edge can propagate through a nonlinear fiber Bragg grating, even if the broadband spectrum of this ultrashort pulse overlaps the whole ...

Fiber Bragg grating technology
Conference Proceedings LEOS'96 9th Annual Meeting IEEE Lasers and Electro-Optics Society, 2002Bragg gratings in fiber and planar waveguides are now coming into practical use for telecommunications, data communications, and signal processing applications. New high power fiber lasers are also using fiber gratings. Various devices for these applications require different types of Bragg gratings.

In many network and sensor applications, small amounts of light need to be coupled out at many points from a transmission bus fiber. In-line devices with some wavelength selectivity are particularly desirable, especially if light radiated from the fiber can be efficiently coupled into another fiber.
