Abstract

Radio frequency (RF) filtering switch is highly desired for signal routing or manipulation in the RF system. Based on the stimulated Brillouin scattering effect and the electro-optics Pockels effect, we propose a novel RF filtering switch with a high-frequency filtering precision and a fast switching speed. We have experimentally demonstrated the RF filtering with a high precision of 34MHz, a wide operation bandwidth of 18GHz, and the RF switching at a speed of <100ps, which is hundreds of times faster than the traditional RF switch.
