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.

纳米光结构实现了许多光学现象和应用。他们目前从高折射率介电介质（例如硅或磷化物）中制造的，在金属，依靠等离子体并因此表现出高欧姆损失的同时构成了限制制造挑战，限制了可实现的应用。在这项工作中，晶体是一类新兴的分层，所谓的范德华（VDW），作为一个可行的纳米光谱平台。在这个项目中，学生将使用这些新颖的VDW材料来设计，制造和研究用于线性和非线性光学应用程序的各种纳米光结构。
