Abstract
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.
