Fundamental limits to multi-functional and tunable nanophotonic response
Hyungki Shim, Zeyu Kuang, Zin Lin +1
Tunable and multi-functional nanophotonic devices are used for applications from beam steering to sensing. Yet little is understood about fundamental limits to their functionality.…
Towards Maximum Optical Efficiency of Ensembles of Colloidal Nanorods
Owen D. Miller, Kyoungweon Park, Richard A. Vaia
Experimental and theoretical studies of colloidal nanoparticles have primarily focused on accurate characterization and simulation of observable characteristics, such as resonant w…
Fundamental limits to the refractive index of transparent optical materials
Hyungki Shim, Francesco Monticone, Owen D. Miller
Increasing the refractive index available for optical and nanophotonic systems opens new vistas for design: for applications ranging from broadband metalenses to ultrathin photovol…
High-NA optical edge detection via optimized multilayer films
Wenjin Xue, Owen D. Miller
There has been a significant effort to design nanophotonic structures that process images at the speed of light. A prototypical example is in edge detection, where photonic-crystal…
