Lasing modes in ZnO nanowires coupled to planar metals
Daniel Repp, Angela Barreda, Francesco Vitale +4
Semiconductor nanowire lasers can be subject to modifications of their lasing threshold resulting from a variation of their environment. A promising choice is to use metallic subst…
Experimental observation of higher-order anapoles in individual silicon disks under in-plane illumination
Evelyn Diaz-Escobar, Angela I. Barreda, Amadeu Griol +1
Anapole states - characterized by a strong suppression of far-field scattering - naturally arise in high-index nanoparticles as a result of the interference between certain multipo…
Hybrid photonic-plasmonic cavity design for very large Purcell factors at telecom wavelengths
Angela Barreda, Laura Mercade, Mario Zapara-Herrera +2
Hybrid photonic-plasmonic cavities can be tailored to display high Q-factors and extremely small mode volumes simultaneously, which results in large values of the Purcell factor, F…
Continuous-Wave Frequency Upconversion with a Molecular Optomechanical Nanocavity
Wen Chen, Philippe Roelli, Huatian Hu +8
Frequency upconversion is a cornerstone of electromagnetic signal processing, analysis and detection. It is used to transfer energy and information from one frequency domain to ano…
Hybrid Photonic-Plasmonic Cavities based on the Nanoparticle-on-a-Mirror Configuration
Angela I. Barreda, Mario Zapata-Herrera, Isabelle Palstra +4
Hybrid photonic-plasmonic cavities have emerged as a new platform to increase light-matter interaction capable to enhance the Purcell factor in a singular way not attainable with e…
Dispersive optomechanics of supercavity modes in high-index disks
Laura Mercadé, Ángela Barreda, Alejandro Martínez
In this work, we study the dispersive coupling between optical quasi-bound-states in the continuum at telecom wavelengths and GHz-mechanical modes in high-index wavelength-sized di…
High-Q transparency band in all-dielectric metasurfaces induced by a quasi bound state in the continuum
Diego R. Abujetas, Angela Barreda, Fernando Moreno +4
Bound states in the continuum (BICs) emerge throughout Physics as leaky/resonant modes that remain however highly localized. They have attracted much attention in Optics and Photon…
Brewster quasi bound states in the continuum in all-dielectric metasurfaces from single magnetic-dipole resonance meta-atoms
Diego R. Abujetas, Angela Barreda, Fernando Moreno +4
Bound states in the continuum (BICs) are ubiquitous in many areas of physics, attracting especial interest for their ability to confine waves with infinite lifetimes. Metasurfaces…
Optical inspection of manufactured nanohole arrays to bridge the lab-industry gap
A. Franco, D. Otaduy, A. I. Barreda +4
Metallic nanohole arrays have shown their potential as sensing tools. Important research supported by sophisticated laboratory experiments have been recently carried out, that may…
Electromagnetic polarization controlled perfect switching effect with high refractive index dimers. the beam-splitter configuration
Angela I. Barreda, Hassan Saleh, Amelie Litman +3
High Refractive Index (HRI) dielectric particles smaller than the wavelength, isolated or forming a designed ensemble are ideal candidates as new multifunctional elements for build…
