摘要	A short pulse generation system and method of generating a short pulse signal are provided. The system includes a fiber chain having an input for receiving an optical signal having a plurality of optical pulses. The fiber chain is nonlinear with respect to the optical signal and includes a first normal fiber segment having a relatively small chromatic parameter, a first abnormal fiber segment having a relatively large chromatic parameter coupled to an output of the first normal fiber segment, and a second abnormal fiber segment having a relatively small chromatic parameter coupled to an out of the first abnormal fiber segment. The system includes a filter stage coupled to an output of the fiber chain and that has a transparent wavelength selected to regenerate the signal. A short pulse signal is produced when the optical signal is coupled to the input.
其他摘要	提供了一种短脉冲发生系统和产生短脉冲信号的方法。该系统包括光纤链，该光纤链具有用于接收具有多个光脉冲的光信号的输入。光纤链相对于光信号是非线性的，并且包括具有相对小的色度参数的第一普通光纤段，具有耦合到第一普通光纤段的输出的相对大的色度参数的第一异常光纤段，以及第二光纤段。具有相对小的色度参数的异常光纤段耦合到第一异常光纤段之外。该系统包括耦合到光纤链的输出的滤波器级，并且具有选择用于再生信号的透明波长。当光信号耦合到输入时产生短脉冲信号。
主权项	A short pulse generation system, comprising: a fiber chain having an input for receiving an optical signal having a plurality of optical pulses, said fiber chain being nonlinear with respect to said optical signal, said fiber chain including: a first normal fiber segment having a relatively small chromatic parameter; a first abnormal fiber segment having a relatively large chromatic parameter coupled to an output of said first normal fiber segment; a second abnormal fiber segment having a relatively small chromatic parameter coupled to an output of said first abnormal fiber segment; and a filter stage coupled to an output of said fiber chain, said filter stage having a transparent wavelength selected to regenerate said optical signal, whereby a short pulse signal is generated when said optical signal is coupled to said input.
