Beyond 50 dB stopband rejection

Abstract

We report a silicon nitride RF photonic notch filter with unprecedented performance including 8 dB of RF gain, record-low noise figure of 15.6 dB, and spurious-free dynamic range of 116 dB while achieving an ultra-deep rejection of beyond 50 dB in the stopbands.
