Abstract

A simple, frequency-multiplied optoelectronic oscillator (OEO) based on a dual-parallel Mach–Zehnder modulator (DPMZM) is proposed and demonstrated. The generated high-frequency microwave signals have improved performance in their phase noise (PN) and signal-to-noise ratio. Two loops (master and slave) are contained in this OEO, each linked to a separate port of the DPMZM. By tuning the voltages of the modulator, a frequency-doubled radio frequency signal is generated in the slave loop and a frequency-quadrupled signal is generated in the master loop. In these experiments, the microwave signals have good performance in purity and PN. The PN of the generated frequency-doubled and frequency-quadrupled signals is −113.3 dBc / Hz@10 kHz and −106.1 dBc / Hz@10 kHz, respectively.
