Passive microwave component design using inverse scattering: theory and applications
(Hindawi, 2013)
info:eu-repo/semantics/article,
We briefly review different synthesis techniques for the design of passive microwave components with arbitrary frequency response,
developed by our group during the last decade. We provide the theoretical foundations based ...
Phase-shift based BOTDA measurements tolerant to non-local effects
(SPIE, 2013)
Contribución a congreso / Biltzarrerako ekarpena,
We demonstrate a BOTDA sensor based on the use of the Brillouin phase shift that performs measurements tolerant to non local effects. This technique raises opportunities to increase the distance covered by these sensors ...
Optimization of sensors based on multimode interference in single-mode–multimode– single-mode structure
(IEEE, 2013)
Artículo / Artikulua,
By coating a single-mode–multimode–single-mode
(SMS) structure with a complex refractive index thin-film the central
wavelength of the transmission and attenuation bands of the
optical spectrum can be shifted. By adequate ...
Experimental demonstration of lossy mode resonance generation for transverse-magnetic and transverse-electric polarizations
(Optica Publishing Group, 2013)
Artículo / Artikulua,
This Letter, presents the fabrication of lossy mode resonance (LMR) devices based on titanium dioxide (TiO2)/ poly(sodium 4-styrenesulfonate) (PSS) coatings deposited on side-polished D-shaped optical fibers. TiO2 thin ...
An easy to deploy street light control system based on wireless communication and LED technology
(MDPI, 2013)
Contribución a congreso / Biltzarrerako ekarpena,
This paper presents an intelligent streetlight management system based on LED lamps, designed to facilitate its deployment in existing facilities. The proposed approach, which is based on wireless communication technologies, ...
Terahertz wave transmission in flexible polystyrene-lined hollow metallic waveguides for the 2.5-5 THz band
(Optical Society of America, 2013)
info:eu-repo/semantics/article,
A low-loss and low-dispersive optical-fiber-like hybrid HE11 mode is developed within a wide band in metallic hollow waveguides if their inner walls are coated with a thin dielectric layer. We investigate terahertz (THz) ...
Tunable electro-optic wavelength filter based on lossy-guided mode resonances
(Optical Society of America, 2013)
info:eu-repo/semantics/article,
In this work an optical fiber tunable filter based on lossy guided-mode resonances (LGMR) is proposed. It consists of a multilayer structure deposited onto the surface of a plastic cladding removed multimode fiber. The ...
Multiplexing of six micro-displacement suspended-core Sagnac interferometer sensors with a Raman-Erbium fiber laser
(Optical Society of America, 2013)
info:eu-repo/semantics/article,
This work experimentally demonstrates a long-range optical
fiber sensing network for the multiplexing of fiber sensors based on
photonic crystal fibers. Specifically, six photonic crystal fiber sensors
which are based ...
Single-longitudinal mode laser structure based on a very narrow filtering technique
(Optical Society of America, 2013)
info:eu-repo/semantics/article,
A narrow filtering technique based on the spectral overlapping of
two uniform FBGs and applied to obtain a Single Longitudinal Mode
(SLM) laser is proposed and demonstrated in this work. The two FBGs are
spectrally ...
Terahertz epsilon-near-zero graded-index lens
(Optical Society of America, 2013)
info:eu-repo/semantics/article,
An epsilon-near-zero graded-index converging lens with planar
faces is proposed and analyzed. Each perfectly-electric conducting (PEC)
waveguide comprising the lens operates slightly above its cut-off frequency
and has ...
