High Performance, Low Noise Figure Brillouin-based Tunable Microwave Photonic Bandpass Filter

We present a high-performance, low-noise figure tunable microwave photonic bandpass filter based on stimulated Brillouin scattering (SBS) loss responses. The bandpass filter response is formed by suppressing the out-of-band signal using multiple broadened SBS loss responses on a high-performance MWP link without introducing additional noise in the passband. A noise figure of 20 dB and -17 dB link gain of 100 MHz passband bandwidth at 14 GHz with spurious free dynamic range of 105 dB.Hz(2/3) are obtained. Multi-bandpass response, bandwidth reconfigurability from 100 MHz to 1 GHz and center frequency tunability up to 16 GHz are also demonstrated.
