Abstract
A method to enhance the filter slope of Brillouin-based photonic microwave filters is presented. This improvement is achieved by the combination of Brillouin gain and loss responses over phase-modulated signals. The experimental results show passband responses exhibiting a slope of 16.7 dB per octave, which corresponds with a threefold improvement in comparison to the natural Lorentzian response for the same gain.This work was supported in part by the Spanish Ministry of Economy and Competitiveness through TEC2016-80906-R project and by the European Union through TWEETHER project.Samaniego-Riera, D.; Vidal Rodriguez, B.
