论文摘要
可以借助为二进制相光栅制定的塔尔伯特阵列照明器的想法来实现具有可变功能比率的方波脉冲产生。 CW激光场的二进制时间相调制通过分数Talbot长度$ p/q $的群 - 隔离 - 分散电路传播的二进制时间相调制，导致方形良好的方波脉冲序列。当$ p = 1 $时，pulses $ d $的值比为$ 1/2 $，$ q = 4 $和$ Q = 3 $和6 $ $ Q = 3 $和6。脉冲双打和三倍的最大强度与$ d = 1/2 $和$ 1/3 $的CW强度相比。这些脉冲可用于光纤通信中的返回到零激光场调制。对于$ d = 1/3 $，发现脉冲之间的额外功能是源自二进制相调制中相位的有限上升和下降时间。对于二元相光栅，预测了类似的效果作为时空类比的好处，并将其解释为矩形相光栅组件不完美的边缘产生的闪光。
Square-wave pulse generation with a variable duty ratio can be realized with the help of ideas of Talbot array illuminators formulated for binary phase gratings. A binary temporal phase modulation of CW laser field propagating through a group-delay-dispersion circuit of the fractional Talbot length $P/Q$ results in a well defined sequence of square-wave-form pulses. When $P=1$ a duty ratio of the pulses $D$ is $1/2$ for $Q=4$ and $1/3$ for $Q=3$ and 6. Maximum intensity of the pulses doubles and triples compared to the CW intensity for $D=1/2$ and $1/3$, respectively. These pulses can be used for return-to-zero laser field modulation in optical fiber communication. For $D=1/3$ extra features between the pulses are found originating from a finite rise and drop time of phase in a binary phase modulation. Similar effect as a benefit of the time-space analogy is predicted for binary phase gratings and interpreted as gleams produced by imperfect edges of the components of the rectangular phase gratings.
