We will investigate the fundamentals of sub-wavelength, fully plasmon-based nonlinear optical processes with the aim of understanding the microscopic origins of nonlinear plasmon-photon interaction and theirdependence on mode hybridization and adiabatic conversion. We will develop and apply the powerful method of two-color k-space spectroscopy with femtosecond laser pulses. This method gives precise measurements ofthe propagation constants of surface plasmons, and yields information on the dynamics of plasmon-plasmon and plasmon-photon interactions. Furthermore, by using a pair of non-degenerate pump pulses, we canexamine optical parametric and four-wave mixing processes and identify the type of plasmon-photon interactions that drive it. The acquired knowledge will be used to develop concepts leading to the demonstration of such compelling devices as a high efficiency "throughput coupler" (combining in- and outcoupling on-a-chip) between confined plasmon modes in nanostructures and far-field optical modes. The dynamics and efficiency of surface plasmon coupling and plasmon propagation in ultrathin metallic films which support mode hybridization will be investigated. A plasmon-based quantum-correlated photon source is the ultimate vision of the project.

我们将研究亚波长，完全基于等离子体激元的非线性光学过程的基本原理，目的是了解非线性等离子体激元-光子相互作用的微观起源及其对模式杂化和绝热转换的依赖性。我们将开发和应用飞秒激光脉冲双色k空间光谱学的强大方法。这种方法给出了表面等离子体的传播常数的精确测量，并产生等离子体激元和等离子体激元光子相互作用的动力学信息。此外，通过使用一对非简并泵浦脉冲，我们可以研究光学参量过程和四波混频过程，并确定驱动它的等离子体-光子相互作用的类型。所获得的知识将用于开发概念，从而导致演示诸如高效“吞吐量耦合器”之类的引人注目的设备在纳米结构中的受限等离子体激元模式和远场光学模式之间的耦合（在芯片上组合入耦合和出耦合）。本文将研究支持模式杂化的金属薄膜中表面等离子体激元耦合和等离子体激元传播的动力学和效率。 基于等离子体激元的量子相关光子源是该项目的最终愿景。
