Abstract :
In this paper, we present a theoretical model of a microwave-photonic link using phase modulation and fiber-Bragg grating optical filter, based on two-tone analysis. The calculation supports the merit of the link by showing optical carrier suppression and third-order intermodulation distortion (IM3) cancellation for small-signal modulation and substantial suppression of IM3 even at high modulation levels. Ideally, the IM3 power decreases more than 75 dB than that without suppression at modulation depth up to 0.5.
