Ultra-flat Brillouin gain spectrum via linear combination of two acoustically anti-guiding optical fibres

A novel approach to broadening and flattening the Brillouin gain spectrum, is presented. A linear combination of two acoustically anti-guiding optical fibres gives rise to a Brillouin spectrum with less than 0.5 dB gain variation over 200 MHz. The fibres are selected, so that they possess individual...

Summary:A novel approach to broadening and flattening the Brillouin gain spectrum, is presented. A linear combination of two acoustically anti-guiding optical fibres gives rise to a Brillouin spectrum with less than 0.5 dB gain variation over 200 MHz. The fibres are selected, so that they possess individual Brillouin spectra that are shifted in frequency from each other, such that a relative maximum of one overlaps with a relative minimum of the other.
