B. Coutinho dos Santos, C. E. R. Souza, K. Dechoum, A. Z. Khoury

摘要:

本文提出了一个轨道角动量注入下光学参量振荡器空间模式动力学的理论模型。这个过程,然后解释一个有趣的图片的基础上庞加莱表示的一阶空间模式。下转换场的空间性质可以很容易地从它们在这种几何表示中的对称性来理解。通过考虑注入信号的绝热模转换,我们还预测了下转换光束中几何相位共轭的发生。提出了一种测量这种效应的实验装置。

英文摘要:

We present a theoretical model for the spatial mode dynamics of an optical parametric oscillator under injection of orbital angular momentum. This process is then interpreted in terms of an interesting picture based on a Poincare representation of first order spatial modes. The spatial properties of the down-converted fields can be easily understood from their symmetries in this geometric representation. By considering the adiabatic mode conversion of the injected signal, we also predict the occurrence of a geometric phase conjugation in the down-converted beams. An experimental setup to measure this effect is proposed.
