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.…
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…
Optical Materials for Maximal Nanophotonic Response
Hyungki Shim, Zeyu Kuang, Owen D. Miller
This article reviews the material properties that enable maximum optical response. We highlight theoretical results that enable shape-independent quantification of material "figure…
Maximal Free-Space Concentration of Electromagnetic Waves
Hyungki Shim, Haejun Chung, Owen D. Miller
We derive upper bounds to free-space concentration of electromagnetic waves, mapping out the limits to maximum intensity for any spot size and optical beam-shaping device. For sub-…
Fundamental limits to near-field optical response, over any bandwidth
Hyungki Shim, Lingling Fan, Steven G. Johnson +1
We develop an analytical framework to derive upper bounds to light--matter interactions in the optical near field, where applications ranging from spontaneous-emission amplificatio…
