Adaptive voltage control of the DC/DC boost stage in PV converters with small input capacitor
(IEEE, 2013)
Artículo / Artikulua,
In the case of photovoltaic (PV) systems, an adequate PV voltage regulation is fundamental in order to both maximize and limit the power. For this purpose, a large input capacitor has traditionally been used. However, when ...
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 ...

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 ...
Highly-efficient fully resonant vertical couplers for InP active-passive monolithic integration using vertically phase matched waveguides
(Optical Society of America, 2013)
info:eu-repo/semantics/article,
A new active-passive monolithic integration approach for
photonic components based on vertical evanescent coupling is presented.
Two vertically stacked waveguides are used in order to provide full
resonant power transfer ...
Characterization of RF-MOSFETs in common-source configuration at different source-to-bulk voltages from S-parameters
(IEEE, 2013)
Artículo / Artikulua,
Using a new test fixture that allows us to bias the bulk terminal through an additional compensated DC probe, a two-port S-measurement-based methodology to characterize RF-MOSFETs in common-source configuration is herein ...
