Electromagnetic arbitrary waveform generation with broadband incoherent light sources
(Optical Society of America, 2008-12)
Optical engineering: new waveform generation provides the experimentalist with interesting new tools
Self-similar focusing with generalized devil’s lenses
(Optical Society of America, 2011)
We introduce the generalized devil’s lenses (GDLs) as a new family of diffractive kinoform lenses whose structure
is based on the generalized Cantor set. The focusing properties of different members of this family are ...
Facile and low-cost fabrication of SiO2-covered Au nanoislands for combined plasmonic enhanced fluorescence microscopy and SERS
(MDPI, 2023-10-08)
An easy and low-cost way to fabricate monometallic Au nanoislands for plasmonic enhanced spectroscopy is presented. The method is based on direct thermal evaporation of Au on glass substrates to form nanoislands, with ...
A note on the p-parabolicity of submanifolds
(Springer Science+Business Media B.V., 2011)
We give a geometric criterion which shows p-parabolicity of a class of submanifolds in a Riemannian manifold, with controlled second fundamental form, for p ≥ 2.
Diffractive optics for spectral control of the supercontinuum generated in sapphire with femtosecond pulses
(Optical Society of America, 2011)
We propose the use of kinoform diffractive lenses to focus near infrared femtosecond pulses in sapphire crystals for supercontinuum generation. It is shown that a strongly peaked structure appears in the blue region of the ...
All-fiber incoherent frequency-to-time mapping method for microwave signal generation with baseband transmission and multicasting support
(Elsevier, 2008)
We present a proof-of-principle experiment for achieving simultaneous distribution of baseband radio-frequency data and up-conversion with broadcasting support over a passive optical network. The technique is based on an ...
Scalable and Efficient Clustering for Fingerprint-Based Positioning
(IEEE, 2023)
Abstract:
Indoor positioning based on IEEE 802.11 wireless LAN (Wi-Fi) fingerprinting needs a reference data set, also known as a radio map, in order to match the incoming fingerprint in the operational phase with the ...
Single-pixel imaging through turbid media by combining a programmable light source and a DMD
(Society of Photo-Optical Instrumentation Engineers (SPIE), 2023-03-15)
Imaging through turbid media remains a relevant topic in biomedical imaging. In this contribution, we propose the combination of frequency domain imaging (SFDI) and single-pixel imaging (SPI) to image objects hidden by a ...
Creating a treadmill running video game with smartwatch interaction
(Springer, 2023)
In recent years, indoor or at-home sports have experienced signifcant growth. However,
monotony is a common challenge in these static physical activities. Exergames, a genre of
video games that combines physical activity ...
Micro-patterns of gold nanoparticles assembled by photovoltaic optoelectronic tweezers: application to plasmonic fluorescence enhancement
(Optica Publishing Group, 2022-10-27)
Noble metal nanostructures are well-known for their ability to increase the efficiency of different optical or physical phenomena due to their plasmonic behavior. This work presents a simple strategy to obtain Au plasmonic ...
