Quantitative quality inspection of large-area plasmonic metasurfaces for optical devices

Masoumeh Goudarzi, Sunghwan Jo, Maira Pérez Sosa, Yu-Chen Wei et autres

Abstract Uniform wafer-scale inspection of periodic nanostructures and metasurfaces is crucial for large-area devices, where even nanometer-scale deviations in dimensions cause detectable changes in their interaction with light. We utilized incident angle-controlled optical scatterometry, implemented on a Fourier microscope, to characterize structural …

Parametric Control of Extrinsic Chiral Response in THz Nonlocal Metasurfaces via Quasi-Bound States in the Continuum

Jie Ji, Niels Van Esseveldt, Djero Peeters, Jaime Gómez Rivas

Abstract Symmetry-protected bound states in the continuum (BICs) exhibit polarization-selective radiation characteristics governed by the symmetry-imposed decoupling from free-space modes. Leveraging this intrinsic property, we demonstrate that controlled symmetry breaking in nonlocal metasurfaces formed by tilted bars converts a symmetry-protected BIC into …

Unconventional Localization of Light with Mie-tronics

Thanh Xuan Hoang, Daniel Leykam, Ayan Nussupbekov, Jie Ji et autres

Spatial localization of light requires high- Q cavities or disorder, yet the wave nature of light may open novel opportunities for the enhanced confinement of light via interference effects. Here we employ the basic concepts of the recently emerged field of Mie-tronics …

All-Optical Control of the Polarization Axis of Polariton Condensates

Jose Sanchez-Gil, Tobias Schneider, José Luis Pura, Jaime Gómez Rivas et autres

Exciton-polariton condensates in optical metasurfaces offer the potential for all-optical information processing through polariton-polariton interactions and their polarization degrees of freedom. We demonstrate all-optical control of the polarization state of a polariton condensate, enabled by tailoring the spatial geometry of the optical …

Data from: Extended nonradiative dipole-dipole energy transfer and spatiotemporal coherence enabled by bound states in the continuum

Wouter Holman, Jie Ji, Jaime Gómez Rivas

Breaking the fundamental distance limit of dipole–dipole interactions is key to enabling scalable quantum and photonic technologies. Conventional non-radiative energy transfer (FRET) is intrinsically confined to deep subwavelength distances, limiting its scalability. Here, we demonstrate millimeter-scale, coherent dipole–dipole energy transfer enabled by …

Perylenediimide‐Siloxane Block Molecules Displaying Circularly Polarized Emission from Achiral Nanostructured Surfaces

Bart W. L. van den Bersselaar, K. Wang, Yu‐Chen Wei, Xiaoke Zhu et autres

The development of organic dyes is crucial for high‐tech technologies such as displays, telecommunication, and anticounterfeiting. While rylene diimides such as naphthalene and perylene diimides (NDIs and PDIs) exhibit promising optical properties, their crystalline and brittle nature can limit their suitability for …

Near-field probing of the local density of optical states enhanced by bound states in the continuum in nonlocal metasurfaces

Jie Ji, Jose Antonio Sánchez-Gil, Djero B. L. Peeters, Wouter Holman et autres

Bound states in the continuum (BICs) are optical modes that remain decoupled from free-space radiation. Symmetry-protected BICs in metasurfaces offer powerful means to control light-matter interactions. A key property governing these interactions is the partial local density of optical states (PLDOS), which …

Mie-tronics supermodes and symmetry breaking in nonlocal metasurfaces

Thanh Xuan Hoang, Ayan Nussupbekov, Jie Ji, Daniel Leykam et autres

It is usually believed that symmetry breaking in photonic systems leads to weaker optical confinement, such as in the case of metasurfaces when bound states in the continuum are replaced by quasi-bound states with lower quality factors (Q factors). Here we show …
