Bragg gratings with directional, efficient, and wavelength-selective fiber outcoupling
Wavelength demultiplexing is a very promising application of photoinduced fiber gratings. In this paper efficient outcoupling of a very narrow wavelength band, in addition to the usual guided Bragg reflection, is presented. The selective outcoupling gratings were fabricated by focusing the irradiation beam to a dimension smaller than the core diameter of a standard fiber. The highly selective outcoupling of such devices might increase the multiplexing density
