我们报道了在单模光纤中通过诱导调制不稳定性在>0.3 THz（可调谐）重复率下产生0.5 ps半峰全宽光脉冲。选择1.319 μm钕：钇铝石榴石激光器作为载波，并通过将其与外光栅腔InGaAsP激光器混合来引入对该载波的初始调制。这种全光调制方案的使用和光纤中的非线性光传播效应（即，调制不稳定性）允许人们进入太赫兹范围，这比受电子有限响应限制的最快数据高出大约两个数量级。
We report the generation of 0.5 ps full width at half‐maximum optical pulses at >0.3 THz (tunable) repetition rate via an induced modulational instability in a single‐mode fiber. A 1.319‐μm neodymium:yttrium aluminum garnet laser is chosen as the carrier wave and the initial modulation on this carrier is introduced by mixing it with an external‐grating‐cavity InGaAsP laser. The use of this all‐optical modulating scheme and the nonlinear optical propagation effect in fiber (i.e., modulational instability) allows one to reach into the terahertz regime, which is about two orders of magnitude beyond the fastest data limited by the finite response of electronics.
