Boosting Sensing Performance through Near-Field Engineering in Low-Q Metasurfaces
José Antonio Álvarez-Sanchis, Luis Manuel Máñez-Espina, Teresa Mengual Chuliá +2
Dielectric metasurfaces have introduced a new paradigm for substance detection by exploiting their resonant properties to enhance light-matter interaction. This enhancement can be…
Strong Mode Coupling via Quasi-Bound States in the Continuum in Bianisotropic Metasurfaces
Luis Manuel Máñez-Espina, Bahman Amrahi, Viktar Asadchy +1
Electromagnetic mode coupling plays a key role in many resonant effects in nanophotonics. This coupling is also responsible for the appearance of bianisotropy, where electric and m…
Giant bias-free nonreciprocity for unpolarized light via synthetic motion
L. M. Máñez-Espina, B. Amrahi, I. Faniayeu +4
Reciprocity breaking at optical frequencies typically relies on bulky magnets, dynamic modulation, or nonlinearities, all of which hinder chip-scale integration and the handling of…
Control of the local and nonlocal electromagnetic response in all-dielectric reconfigurable metasurfaces
Luis Manuel Máñez-Espina, Ana Díaz-Rubio
Reconfigurable metasurfaces are potent platforms to control the propagation properties of light dynamically. Among different reconfiguration mechanisms available at optical frequen…
Broadband transparent Huygens' spaceplates
Francisco J. Díaz-Fernández, Luis Manuel Máñez-Espina, Ana Díaz-Rubio +1
Spaceplates have emerged in the context of nonlocal metasurfaces, enabling the compression of optical systems by minimizing the required empty space between their components. In th…
