Abstract
A wideband microwave regenerative frequency divider with tunable division factors is proposed and experimentally demonstrated based on harmonic mixing in an optoelectronic oscillator. In the optoelectronic oscillation cavity, a phase modulator is cascaded with an optical filter to achieve equivalent intensity modulation by preserving the single sideband. Harmonic mixing procedure occurs between the $+ 1^{\mathrm {st}}$ -order sideband of the input signal and the higher-order sideband of the oscillation signal within the following photodetector. When the intermediate frequency generated by the harmonic mixing procedure matches the oscillation frequency, and the loop phase and gain conditions are satisfied, microwave regenerative frequency division can be achieved. The frequency division factor is determined by the order of the optical sideband of the oscillation signal during the harmonic mixing and can be adjusted using a two-tap microwave filter constructed with a phase shifter on each arm. Experimental results show that a microwave regenerative frequency divider with an operating frequency range of 22 to 30 GHz and division factors varying from 2 to 8 was successfully realized.
期刊介绍:
IEEE Photonics Technology Letters addresses all aspects of the IEEE Photonics Society Constitutional Field of Interest with emphasis on photonic/lightwave components and applications, laser physics and systems and laser/electro-optics technology. Examples of subject areas for the above areas of concentration are integrated optic and optoelectronic devices, high-power laser arrays (e.g. diode, CO2), free electron lasers, solid, state lasers, laser materials'' interactions and femtosecond laser techniques. The letters journal publishes engineering, applied physics and physics oriented papers. Emphasis is on rapid publication of timely manuscripts. A goal is to provide a focal point of quality engineering-oriented papers in the electro-optics field not found in other rapid-publication journals.
