Strong suppression of the photonic density of states in three-dimensional disordered silicon networks
Abraham Aguilar Uribe, Francisco Hernández Alejandre, Mattis Reisner +4
Photonic bandgaps can open not only in crystalline dielectric materials but also in amorphous structures. Self-uniform amorphous gyroid networks have been proposed as promising dis…
Bandgap fluctuations and robustness in two-dimensional hyperuniform dielectric materials
Luis S. Froufe-Pérez, Geoffroy Aubry, Frank Scheffold +1
We numerically study the statistical fluctuations of photonic band gaps in ensembles of stealthy hyperuniform disordered patterns. We find that at low stealthiness, where correlati…
Angular resolved light scattering from micron-sized colloidal assemblies
Pavel Yazhgur, Geoffroy J. Aubry, Luis S. Froufe +1
Disordered dielectrics with structural correlations on length scales comparable to visible light wavelengths exhibit complex optical properties. Such materials exist in nature, lea…
Transition from Light Diffusion to Localization in Three-Dimensional Amorphous Dielectric Networks near the Band Edge
Jakub Haberko, Luis S. Froufe-Pérez, Frank Scheffold
Localization of light is the photon analog of electron localization in disordered lattices for whose discovery Anderson received the Nobel prize in 1977. The question about its exi…
Light induced "Mock Gravity" at the nanoscale
Jorge Luis-Hita, Manuel I. Marques, Rafael Delgado-Buscalioni +4
The origin of long-range attractive interactions has fascinated scientist along centuries. The remarkable Fatio-LeSage's corpuscular theory, introduced as early as in 1690 and gene…
Transport Phase Diagram and Anderson Localization in Hyperuniform Disordered Photonic Materials
Luis S. Froufe-Pérez, Michael Engel, Juan José Sáenz +1
Hyperuniform disordered photonic materials (HDPM) are spatially correlated dielectric structures with unconventional optical properties. They can be transparent to long-wavelength…
Magneto-Optical Activity in High Index Dielectric Nanoantennas
N. de Sousa, L. S. Froufe-Pérez, J. J. Sáenz +1
The magneto-optical activity, namely the polarization conversion capabilities of high-index, non-absorbing, core-shell dielectric nanospheres is theoretically analyzed. We show tha…
The Role of Short-Range Order and Hyperuniformity in the Formation of Band Gaps in Disordered Photonic Materials
Luis S. Froufe-Pérez, Michael Engel, Pablo F. Damasceno +4
We study photonic band gap formation in two-dimensional high refractive index disordered materials where the dielectric structure is derived from packing disks in real and reciproc…
High-quality photonic crystals with a nearly complete band gap obtained by direct inversion of woodpile templates with titanium dioxide
Catherine Marichy, Nicolas Muller, Luis S. Froufe-Pérez +1
Photonic crystal materials are based on a periodic modulation of the dielectric constant on length scales comparable to the wavelength of light. These materials can exhibit photoni…
Controlling dispersion forces between small particles with artificially created random light fields
Georges Bruegger, Luis Froufe-Perez, Frank Scheffold +1
Appropriate combinations of laser beams can be used to trap and manipulate small particles with "optical tweezers" as well as to induce significant "optical binding" forces between…
Localized magnetic plasmons in all-dielectric mu<0 metastructures
R. Paniagua-Dominguez, L. S. Froufe-Perez, J. J. Saenz +1
Metamaterials are known to exhibit a variety of electromagnetic properties non-existing in nature. We show that an all-dielectric (non-magnetic) system consisting of deep subwavele…
Self-diffusion and structural properties of confined fluids in dynamic coexistence
N. de Sousa, J. J. Sáenz, Frank Scheffold +2
Self-diffusion and radial distribution functions are studied in a strongly confined Lennard-Jones fluid. Surprisingly, in the solid-liquid phase transition region, where the system…
Broadband telecom transparency of semiconductor-coated metal nanowires: more transparent than glass
R. Paniagua-Domínguez, D. R. Abujetas, L. S. Froufe-Pérez +2
Metallic nanowires (NW) coated with a high permittivity dielectric are proposed as means to strongly reduce the light scattering of the conducting NW, rendering them transparent at…
Negative scattering asymmetry parameter for dipolar particles: Unusual reduction of the transport mean free path and radiation pressure

We establish a relationship between the electric magnetic dipole interaction force from a plane wave on a small magnetodielectric particle, the transport cross-section and the scat…

High-permittivity dielectric particles with resonant magnetic properties are being explored as constitutive elements of new metamaterials and devices in the microwave regime. Magne…
Threshold of a Random Laser with Cold Atoms
Luis S. Froufe-Pérez, William Guerin, Rémi Carminati +1
We address the problem of achieving an optical random laser with a cloud of cold atoms, in which gain and scattering are provided by the same atoms. The lasing threshold can be def…
Statistical Scattering of Waves in Disordered Waveguides: from Microscopic Potentials to Limiting Macroscopic Statistics

We study the statistical properties of wave scattering in a disordered waveguide. The statistical properties of a "building block" of length (delta)L are derived from a potential m…

Gabriel Cwilich, Luis S. Froufe-Perez, Juan Jose Saenz
Spatial intensity correlations between waves transmitted through random media are analyzed within the framework of the random matrix theory of transport. Assuming that the statisti…
