Van der Waals nanophotonics

纳米光子结构使许多光学现象和应用成为可能。他们目前使用高折射率介质（如硅或磷化镓）制造，这对制造构成了限制，而金属依赖于等离子体，因此表现出高欧姆损耗，限制了可实现的应用。在这项工作中，一种新兴的层状，所谓的范德华（vdW）晶体被认为是一种可行的纳米光子学平台。在这个项目中，学生将使用这些新颖的vdW材料来设计、制造和研究广泛的线性和非线性光学应用的纳米光子结构。

Numerous optical phenomena and applications have been enabled by nanophotonic structures. Their current fabrication from high refractive index dielectrics, such as silicon or gallium phosphide, pose restricting fabrication challenges while metals, relying on plasmons and thus exhibiting high ohmic losses, limit the achievable applications. An emerging class of layered, so-called van der Waals (vdW), crystals is presented as a viable nanophotonics platform in this work. In this project the student will use these novel vdW materials to design, fabricate and investigate a wide range of nanophotonic structures for linear and nonlinear optics applications.
