Photonic bands, superchirality, and inverse design of a chiral minimal metasurface
Simone Zanotto, Giacomo Mazzamuto, Francesco Riboli +4
Photonic band structures are a typical fingerprint of periodic optical structures, and are usually observed in spectroscopic quantities such as transmission, reflection and absorpt…
Optimized White Reflectance in Photonic Network Structures
Francesco Utel, Lorenzo Cortese, Diederik S. Wiersma +1
Three-dimensional disordered networks are receiving increasing attention as versatile architectures for highly scattering materials. However, due to their complex morphology, littl…
Bow-Tie Cavity for Terahertz Radiation
Luigi Consolino, Annamaria Campa, Davide Mazzotti +3
We report on the development, testing, and performance analysis of a bow-tie resonant cavity for terahertz (THz) radiation, injected with a continuous-wave 2.55 THz quantum cascade…
Fully phase-stabilized quantum cascade laser frequency comb
Luigi Consolino, Malik Nafa, Francesco Cappelli +8
Optical frequency comb synthesizers (FCs) [1] are laser sources covering a broad spectral range with a number of discrete, equally spaced and highly coherent frequency components,…
Structured Optical Materials Controlled by Light
Sara Nocentini, Daniele Martella, Camilla Parmeggiani +2
Materials of which the optical response is determined by their structure are of much interest both for their fundamental properties and applications. Examples range from simple gra…
Directionality Fields generated by a Local Hilbert Transform
W. W. Ahmed, R. Herrero, M. Botey +3
We propose a new approach based on a local Hilbert transform to design non-Hermitian potentials generating arbitrary vector fields of directionality, p(r), with desired shapes and…
Diffusion of light in semitransparent media
Lorenzo Pattelli, Giacomo Mazzamuto, Diederik Wiersma +1
Light diffusion is usually associated with thick, opaque media. Indeed, multiple scattering is necessary for the onset of the diffusive regime and such condition is generally not m…
Deducing effective light transport parameters in optically thin systems
Giacomo Mazzamuto, Lorenzo Pattelli, Costanza Toninelli +1
We present an extensive Monte Carlo study on light transport in optically thin slabs, addressing both axial and transverse propagation. We completely characterize the so-called bal…
Spatio-temporal visualization of light transport in complex photonic structures
Lorenzo Pattelli, Romolo Savo, Matteo Burresi +1
Spatio-temporal imaging of light propagation is very important in photonics because it provides the most direct tool available to study the interaction between light and its host e…
Path length enhancement in disordered media for increased absorption
Rajeshkumar Mupparapu, Kevin Vynck, Tomas Svensson +2
We theoretically and numerically investigate the capability of disordered media to enhance the optical path length in dielectric slabs and augment their light absorption efficiency…
A compact ultranarrow high-power laser system for experiments with 578nm Ytterbium clock transition
Giacomo Cappellini, Pietro Lombardi, Marco Mancini +4
In this paper we present the realization of a compact, high-power laser system able to excite the Ytterbium clock transition at 578 nm. Starting from an external-cavity laser based…
Detection of weak stochastic force in a parametrically stabilized micro opto-mechanical system
A. Pontin, M. Bonaldi, A. Borrielli +5
Measuring a weak force is an important task for micro-mechanical systems, both when using devices as sensitive detectors and, particularly, in experiments of quantum mechanics. The…
Walk dimension for light in complex disordered media
Romolo Savo, Matteo Burresi, Tomas Svensson +2
Transport in complex systems is characterized by a fractal dimension -- the walk dimension -- that indicates the diffusive or anomalous nature of the underlying random walk process…
Robust frequency stabilization of multiple spectroscopy lasers with large and tunable offset frequencies
Alexander Nevsky, Soroosh Alighanbari, Qun-Feng Chen +7
We demonstrate a compact and robust device for simultaneous absolute frequency stabilization of three diode lasers whose carrier frequencies can be chosen freely relative to the re…
Experimental and theoretical investigation of statistical regimes in random laser emission
Emilio Ignesti, Federico Tommasi, Lorenzo Fini +4
We present a theoretical and experimental study aimed at characterizing statistical regimes in a random laser. Both the theoretical simulations and the experimental results show th…
Light transport and localization in two-dimensional correlated disorder
Gaurasundar M. Conley, Matteo Burresi, Filippo Pratesi +2
Structural correlations in disordered media are known to affect significantly the propagation of waves. In this article, we theoretically investigate the transport and localization…
Optical non-reciprocity of cold atom Bragg mirrors in motion
S. A. R. Horsley, J. -H. Wu, M. Artoni +1
Reciprocity is fundamental to light transport and is a concept that holds also in rather complex systems. Yet, reciprocity can be switched off even in linear, isotropic and passive…
Revisiting the Bragg reflector to illustrate some modern developments in optics
S. A. R. Horsley, J. -H. Wu, M. Artoni +1
A series of thin layers of alternating refractive index is known to make a good optical mirror over certain bands of frequency. Such a device - often termed the Bragg reflector - i…
Two-dimensional disorder for broadband, omnidirectional and polarization-insensitive absorption
Matteo Burresi, Filippo Pratesi, Kevin Vynck +3
The surface of thin-film solar cells can be tailored with photonic nanostructures to allow light trapping in the absorbing medium. This in turn increases the optical thickness of t…
Metallo-dielectric hybrid antennas for ultrastrong enhancement of spontaneous emission
Xue-Wen Chen, Mario Agio, Vahid Sandoghdar
We devise new optical antennas that reduce the excited-state radiative lifetimes of emitters to the order of 100 femtoseconds while maintaining quantum efficiencies of about 80% at…

It is known that compaction of granular matter can lead to anisotropic mechanical properties. Recent work has confirmed the link to pore space anisotropy, but the relation between…
Radiation pressure on a moving body: beyond the Doppler effect
S. A. R. Horsley, M. Artoni, G. C. La Rocca
The dependence of macroscopic radiation pressure on the velocity of the object being pushed is commonly attributed to the Doppler effect. This need not be the case, and here we hig…
