摘要:

借助全数控光频梳生成技术,提出了一种基于受激布里渊散射效应的可编程微波光子滤波方案.对该方案的原理和结构进行分析并建立了可编程滤波模型,通过实验进行验证,获得了滤波带宽0.1~1 GHz范围内可调、顶部通带响应相对平坦、可重构、中心频率可在4~24 GHz大范围内连续调谐的微波光子滤波器.该滤波方案与已有的模拟控制的微波光子滤波方案相比,具有全数控可编程的优良特性.

Abstract:

In this paper, using a fully digital programmable optical frequency comb, a new kind of programmable microwave photonic filter based on stimulated Brillouin scattering is proposed. The principle and experiments scheme are described according to the filtering model established. In experiments, a reconfigurable microwave photonic filter is achieved, showing a tunable range of 0.1~1 GHz, flat top of passband responses and tunable central frequency in a large range of 4~24 GHz. Compared with the microwave photonic filters based on analog signal control, this microwave photonic filter scheme is fully digitally controlled and programmable.

Key words: Microwave photonic filter, Stimulated Brillouin scattering, Optical frequency comb, Phase modulation, Microwave photonic
