摘　　要：根据非相干光传输理论,对光强调制信号在光纤干涉器中的传输过程进行较系统理论分析和计算机仿真,得到了微波信号在光纤Mach-Zenhder光纤滤波器、单耦合器光纤谐振环和双耦合器光纤谐振环中的传递函数,采用数字滤波器的理论方法,给出了相应器件取得零点、极点所需要的条件,并据此详细分析了光纤干涉器中的微波频谱特性,为不同类型微波光子滤波器的设计提供了结构和理论基础.The transmission of the optical intensity modulation signal in optical fiber interferometer is investigated by calculation and computer simulation according to the optical incoherent theory. The transfer functions of microwave signals transfer in Mach-Zenhder optical fiber filter,single-coupler optical fiber ring and double-coupler fiber optical ring are obtained and the conditions of poles and zeros are given. Ffurthermore,the microwave frequency spectrum characteristics of the optical fiber interferometer are detailed analysised. The research provides the structure and theoretical basis for the design of different types of microwave photonic filters.
