Abstract

A photonic approach to generate tunable microwave signal with frequency-multiplication is proposed. In the proposed scheme, the microwave signal with tunable fundamental frequency is generated by an optoelectronic oscillator (OEO) incorporating a tunable microwave photonic bandpass filter. Then a stimulated Brillouin scattering (SBS) assisted notch filter is used to achieve wavelength-independent optical carrier suppressing for frequency multiplication. In the experiment, the frequency-doubled microwave signals with a tunable range from 15 GHz to 25 GHz and frequency-quadrupled signals with frequencies of 8 and 12 GHz are generated..
