Freeform Diffractive Metagrating Design Based on Generative Adversarial Networks
Jiaqi Jiang, David Sell, Stephan Hoyer +3
A key challenge in metasurface design is the development of algorithms that can effectively and efficiently produce high performance devices. Design methods based on iterative opti…
Freeform metagratings based on complex light scattering dynamics for extreme, high efficiency beam steering
Jianji Yang, David Sell, Jonathan A. Fan
Conventional phased-array metasurfaces utilize resonant nanoparticles or nanowaveguides to specify spatially-dependent amplitude and phase responses to light. In nearly all these i…
Simple analytical expression for the peak-frequency shifts of plasmonic resonances for sensing
Jianji Yang, Harald Giessen, Philippe Lalanne
We derive a closed-form expression that accurately predicts the peak frequency-shift and broadening induced by tiny perturbations of plasmonic nanoresonators without critically rel…
Theory of fishnet negative-index optical metamaterials
J. Yang, C. Sauvan, H. T. Liu +1
We theoretically study fishnet metamaterials at optical frequencies. In contrast to earlier works, we provide a microscopic description by tracking the transversal and longitudinal…
Metal-coated nano-cylinder cavity for broadband nonclassical light emission
I. Maksymov, Mondher Besbes, Jean-Paul Hugonin +5
A novel metal-coated nanocylinder-cavity architecture fully compatible with III-V GaInAs technology and benefiting from a broad spectral range enhancement of the localdensity- of-s…
