讨论了两种基于单马赫-曾德尔调制器的非归零（NRZ）电信号驱动的光归零（RZ）调制技术。这两种方法都允许连续电可调占空比，并导致啁啾RZ格式。我们演示和讨论了两个RZ发射机设置，产生光RZ信号与电气连续可调的占空比使用一个单一的，NRZ驱动的马赫-曾德尔调制器。
Two optical return-to-zero (RZ) modulation techniques are discussed, both based on a single Mach-Zehnder modulator driven by non-return-to-zero (NRZ) electrical signals. Both methods allow for continuously electrically tunable duty cycles and lead to chirped RZ formats. We demonstrate and discuss two RZ transmitter setups that generate optical RZ signals with electrically continuously tunable duty cycle using a single, NRZ-driven Mach-Zehnder modulator.
