耦合光纤环中离散Angular Momentum的调制不稳定性

Modulation Instability of Discrete Angular Momentum in Coupled Fiber Rings

Calum Maitland, Daniele Faccio, Fabio Biancalana

摘要:

本文分析了耦合光纤环形阵列中的时间调制不稳定性。连续波信号被证明是不稳定的扰动进行离散角动量,正常和异常的群速度色散。我们发现,调制不稳定性的频谱是不同的每一个扰动角动量和强烈地依赖于光纤之间的耦合强度的环。扭转环形阵列还允许通过诱导隧穿Peierls相位调谐频谱。

英文摘要:

We present an analysis of temporal modulation instability in a ring array of coupled optical fibers. Continuous-wave signals are shown to be unstable to perturbations carrying discrete angular momenta, both for normal and anomalous group velocity dispersion. We find the frequency spectrum of modulation instability is different for each perturbation angular momentum and depends strongly on the coupling strength between fibers in the ring. Twisting the ring array also allows the frequency spectra to be tuned through the induced tunnelling Peierls phase.
