多模光纤中的模式动力学

Modal dynamics in multimode fibers

Moti Fridman, Haim Suchowski, Micha Nixon, Asher A. Friesem, Nir Davidson

摘要:

从实验和理论上研究了多模光纤中模式及其偏振态随时间、空间和波长的变化规律。结果表明,改变入射光的偏振角取向时,庞加莱球表象中的偏振态发生位移。这种位移,这使得解释的结果复杂化,克服了诉诸修改庞加莱球表示。通过这样的修改,当输入模式和偏振态已知时,应该可以预测输出模式和它们的偏振态。

英文摘要:

The dynamics of modes and their states of polarizations in multimode fibers as a function of time, space, and wavelength are experimentally and theoretically investigated. The results reveal that the states of polarizations are displaced in Poincare sphere representation when varying the angular orientations of the polarization at the incident light. Such displacements, which complicates the interpretation of the results, are overcome by resorting to modified Poincare spheres representation. With such modification it should be possible to predict the output modes and their state of polarization when the input mode and state of polarization are known.
