Narrow-band Bragg filters for the 1.5-{mu}m spectral region based on polished-side single-mode silica fibres

Narrow-band reflecting filters for the telecommunication 1.5-{mu}m wavelength region are fabricated. They consist of a single-mode silica fibre with a polished side and a periodic relief Bragg grating located in the region of the fibre-mode propagation. The filters have the reflectivity R > 98 %...

Description
Summary:Narrow-band reflecting filters for the telecommunication 1.5-{mu}m wavelength region are fabricated. They consist of a single-mode silica fibre with a polished side and a periodic relief Bragg grating located in the region of the fibre-mode propagation. The filters have the reflectivity R > 98 % and an almost rectangular reflection band with a width of 0.58 - 0.78 nm. They can be used as elements of optical multiplexers/demultiplexers for combining and separating signals in high-speed multichannel fibreoptic communication lines. (fibre optics)
