Tilted black-Si: ~0.45 form-birefringence from sub-wavelength needles
(2020-05-25)
Article
Open AccessThe self-organised conical needles produced by plasma etching of silicon (Si), known as black silicon (b-Si), create a form-birefringent surface texture when etching of Si orientated at angles of ¿i¿<¿50¿-¿70° (angle between ... -
Experimental observation of flat focusing mirror based on photonic jet effect
(Nature, 2020-12-01)
Article
Open AccessIn this work, we experimentally demonstrate that a thin rectangle dielectric-metal structure can have a function of a flat focusing mirror based on photonic jet effect in reflection mode. Using polydimethylsiloxane (PDMS) ... -
Electrodynamics of conductive oxides: intensity-dependent anisotropy, reconstruction of the effective dielectric constant, and harmonic generation
(2020-05-13)
Article
Open AccessWe study electromagnetic pulse propagation in an indium tin oxide nanolayer in the linear and nonlinear regimes. We use the constitutive relations to reconstruct the effective dielectric constant of the medium, and show ... -
Stabilized narrow-beam emission from broad-area semiconductor lasers
(2020-03-20)
Article
Open AccessWe provide a feasible and compact scheme to control and stabilize the spatiotemporal dynamics of broad-area semiconductor (BAS) lasers. The proposal is based on the ability of non-Hermitian potentials with given local ... -
Remote recovery of audio signals from videos of optical speckle patterns: a comparative study of signal recovery algorithms
(2020-03-16)
Article
Open AccessOptical remote sensors are nowadays ubiquitously used, thanks to unprecedented advances in the last decade in photonics, machine learning and signal processing tools. In this work we study experimentally the remote recovery ... -
Optically-thin broadband graphene-membrane photodetector
(2020-03-01)
Article
Open AccessA broadband graphene-on-Si3N4-membrane photodetector for the visible-IR spectral range is realised by simple lithography and deposition techniques. Photo-current is produced upon illumination due to presence of the build-in ... -
Characterizing signal encoding and transmission in class i and class II neurons via ordinal time-series analysis
(Institute of Physics (IOP), 2020-01-16)
Article
Restricted access - publisher's policyNeurons encode and transmit information in spike sequences. However, despite the effort devoted to understand the encoding and trans-mission of information, the mechanisms underlying the neuronal encoding are not yet fully ... -
Inferring the connectivity of coupled oscillators and anticipating their transition to synchrony through lag-time analysis
(2020-04-13)
Article
Restricted access - publisher's policyThe synchronization phenomenon is ubiquitous in nature. In ensembles ofcoupled oscillators, explosive synchronization is a particular type of transition tophase synchrony that is first-order as the coupling strength ... -
In situ decolorization monitoring of textile dyes for an optimized UV-LED/TiO2 reactor
(2019-08-01)
Article
Open AccessHeterogeneous photocatalysis, using photocatalysts in suspension to eliminate diverse contaminants, including textile wastewater, has several advantages. Nevertheless, current absorbance and decolorization measurements ... -
Performance analysis and methodology for replacing conventional lamps by optimized LED arrays for photocatalytic processes
(2020-04-01)
Article
Restricted access - publisher's policyOne of the main drawbacks of heterogeneous photocatalysis is the high consumption of electrical energy generated by conventional lamps. This study proposes a methodology to find the best distribution of light emitting ... -
Mapping atmospheric waves and unveiling phase coherent structures in a global surface air temperature reanalysis dataset
(Institute of Physics (IOP), 2020-01-23)
Article
Restricted access - publisher's policyIn the analysis of empirical signals, detecting correlations that capture genuine interactions between the elements of a complex system is a challenging task with applications across disciplines. Here, we analyze a global ... -
Defect reconstruction by non-destructive testing with laser induced ultrasonic detection
(2020-02)
Article
Restricted access - publisher's policyThis work envisages a detailed study of two-dimensional defect localization and reconstruction, using laser generated ultrasound and its application as a remotely controlled non-destructive testing method. As an alternative ...
