摘要: 针对光纤Mach-Zehnder干涉(MZI)受环境影响的稳定性问题,设计了光纤MZI实验装置。从理论上分析了光纤MZI的输出光强,并给出了实验验证,由示波器直观地显示出光纤MZI的稳定性与环境的关系以及相位调制对干涉的影响等。为了解决振动噪声、温度变化等环境因素导致的光纤MZI不稳定,设计了一种新的相位补偿方案,即用两个2×2光纤耦合器的输出,实现相差检测及反馈控制。

Abstract: In view of the stability problem that the optical fiber Mach-Zehnder interference (MZI) is easily impacted by the environment, the MZI experiment system has been designed. The output intensity of the optical fiber MZI is analyzed theoretically and validated by experiment. The relationship between the stability of the MZI and the environment and the impact of phase modulation on the interference are also revealed intuitively by the oscilloscope. A new phase compensation scheme is designed to solve the instability which results from vibration noise, temperature variation and so forth. The scheme can realize phase difference detection and feedback control.

Key words: laser techniques, phase compensation, optical fiber Mach-Zehnder interference, phase modulation
