Optimization of Phase Noise of Opto-Electronic Oscillator Through Low-Biasing Technology for Modulator
A novel method for reducing the phase noise of the opto-electronic oscillator (OEO) is proposed and experimentally demonstrated. As for a given single-loop OEO, its phase noise characteristics are determined by the noise-to-signal ratio (NSR) which can be reduced by optimizing the direct current (DC) bias voltage of the modulator. Results show that, when the injected optical power equals to 60 mW, the minimum single sideband (SSB) phase noise at the low bias point is gotten which decreases by 2.8 dB than that at the quadrature bias point of the electro-optic modulator.
