Nonlinear nanooptics with spin waves

本计画的主要目的是研究非线性自旋波在横向图案化磁性奈米结构中的传播。本文将研究不同维数微波导中的非线性自旋波光学效应和参数泵浦闭环波导中持续非线性波对象的性质。这些研究将开辟一个新的研究领域，我们称之为“非线性自旋波纳米光学”。所提出的研究将有助于普遍的非线性现象，如孤子，调制不稳定性，图案的形成，和动态混沌的基础物理。此外，它们有望为微电子器件中磁性纳米结构应用中自旋波的操纵、放大和传输开辟新的可能性。该项目汇集了两个世界领先的研究小组，在磁动力学和图案化磁性纳米结构方面拥有独特的经验。

The main goal of this project is to study nonlinear spin-wave propagation in laterally patterned magnetic nanostructures. Nonlinear spin-wave optical effects in micro-waveguides of different dimensionalities and properties of persistent nonlinear wave objects in parametrically pumped closed-loop nanowaveguides will be investigated. These studies will open a new research field, which we call “nonlinear spin-wave nanooptics”. The proposed investigations will contribute to the basic physics of universal nonlinear phenomena, such as solitons, modulational instabilities, pattern formation, and dynamic chaos. Besides, they are expected to open new possibilities for manipulation, amplification, and transmission of spin waves to be used in applications of magnetic nanostructures in microelectronic devices. The project brings together two world-leading research groups, possessing a unique experience in both magnetic dynamics and in patterned magnetic nanostructures.
