Accelerating Adjoint Variable Method Based Photonic Optimization with Schur Complement Domain Decomposition
Nathan Zhao, Salim Boutami, Shanhui Fan
Adjoint variable method in combination with gradient descent optimization has been widely used for the inverse design of nanophotonic devices. In many of such optimizations, the de…

Penetration depth reduction with plasmonic metafilms
Nathan Z. Zhao, Ian A. D. Williamson, Zhexin Zhao +2
In many optical systems, including metal films, dielectric reflectors, and photonic crystals, electromagnetic waves can experience evanescent decay. The spatial length scale of suc…

High reflection from a one-dimensional array of graphene nanoribbons
Nathan Zhao, Zhexin Zhao, Ian Williamson +3
We show that up to 90% reflectivity can be achieved by using guided plasmonic resonances in a one-dimensional periodic array of plasmonic nanoribbon. In general, to achieve strong…
