In this paper we realize an RF photonic chirp compression system that compresses a continuous stream of incoming RF data (modulated on top of an optical carrier) into a train of temporal short pulses. Each pulse in the train can be separated and treated individually while being sampled by low rate optical switch and without temporal loses of the incoming flow of information. Each such pulse can be filtered and analyzed differently. The main advantage of the proposed system is its capability of being able to handle, seamlessly, high rate information flow with all-optical means and with low rate optical switches.
在本文中，我们实现了一种射频光子啁啾压缩系统，该系统将连续输入的射频数据（调制在光载波之上）压缩成一串时间短脉冲。脉冲串中的每个脉冲在通过低速光开关采样时可以被分离并单独处理，同时不会造成输入信息流的时间损失。每个这样的脉冲都可以进行不同的滤波和分析。所提出系统的主要优点在于其能够通过全光手段和低速光开关无缝处理高速信息流。
