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.Reserva de todos los derechosScatteringMicrowave filtersMicrowave photonicsRadio frequencyOptical fiber filtersAmplitude modulationNonlinear effectsFiber non-linear opticsTEORIA DE LA SEÑAL Y COMUNICACIONESArtículo10.1109/JPHOT.2016.2634782Abierto
