【摘要】 利用萨格纳克光纤环的延时和干涉现象,结合单波导调制器的相位调制,设计了一种稳定可调的光脉冲发生装置。该装置可通过设计光纤环的长度以及调节外加调制信号的频率,产生脉冲宽度和重复频率可调的光脉冲输出。详细叙述了该装置的调制原理和参数,并进行了实验验证,实现了100纳秒的稳定光脉冲输出。更多还原

【Abstract】 A stable tunable optical pulse generation device is designed based on the delay and interference effect in Sagnac fiber loop and phase modulation of single-waveguide modulator.Pulse width and its repetition rate change with the length of fiber loop and the frequency of the modulation signal respectively.The principles of modulation and parameters of the device is described in detail .Experiment results is analyzed and discussed and 100ns optical pulse is achieved.更多还原
