A frequency-multiplying radio frequency (RF) source based on the optoelectronic oscillator (OEO) with low phase noise has been proposed and experimentally demonstrated. With the optical carrier suppression process, the frequency quadrupling can be achieved by biasing the intensity modulators at the minimum transmission point simultaneously inside and outside the OEO loop. In the proof-of-concept experiment,...
A novel photonic frequency-doubling up-convertor with compensation of chromatic-dispersion-induced power fading is proposed and experimentally demonstrated based on the cascaded structure of a Mach–Zehnder modulator (MZM) and a dual-parallel Mach–Zehnder modulator (DPMZM). The MZM is driven by a local oscillator signal biased at the null point for carrier-suppressed double-sideband modulation. The...
