    • A pulsed fiber generator is configured with a unidirectional ring waveguide configured to emit a train of pulses. The ring waveguide includes multiple fiber amplifiers, chirping fiber components coupled to respective outputs of first and second fiber amplifiers, and multiple spectral filters coupled to respective outputs of the chirping components. The filters have respective spectral band passes centered around different central wavelengths so as to provide leakage of light along the ring cavity in response to nonlinear processes induced in the ring cavity. The pulse generator operates at a preliminary stage during which it is configured to develop a pitch to a signal, and at a steady stage during which it is configured to output a train of pulses through an output coupler at most once per a single round trip of the signal.
    • 脉冲光纤发生器配置有配置成发射脉冲串的单向环形波导。 环形波导包括多个光纤放大器,耦合到第一和第二光纤放大器的相应输出的线性调频光纤部件,以及耦合到线性调频部件的相应输出的多个光谱滤波器。 滤光器具有以不同中心波长为中心的各自的光谱带通,以响应环形腔中感应的非线性过程而沿环形腔提供光泄漏。 脉冲发生器在初始阶段工作,在此阶段中,其被配置为产生信号间距,并且在稳定阶段,其被配置为通过输出耦合器输出脉冲串至多每一次往返 信号。
