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 ...
Long-range hybrid network with point and distributed Brillouin sensors using Raman amplification
(Optical Society of America, 2010)
info:eu-repo/semantics/article,
We propose a novel concept for hybrid networks that combine
point and distributed Brillouin sensors in a cost-effective architecture that
also deploys remote distributed Raman amplification to extend the sensing
range. A ...
Millimeter-wave phase resonances in compound reflection gratings with subwavelength grooves
(Optical Society of America, 2010)
info:eu-repo/semantics/article,
Experimental evidence of phase resonances in a dual-period
reflection structure comprising three subwavelength grooves in each
period is provided in the millimeter-wave regime. We have analyzed and
measured the response ...
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 ...
Suspended-core fiber Sagnac combined dual-random mirror Raman fiber laser
(Optical Society of America, 2011)
info:eu-repo/semantics/article,
In the present work, a multiwavelength fiber laser based in the
combination of a double-random mirror and a suspended-core Sagnac
interferometer is presented. The double-random mirror acts by itself as a
random laser, ...
Vertically coupled microring resonators using one epitaxial growth step and single-side lithography
(Optical Society of America, 2015)
info:eu-repo/semantics/article,
A new concept for the fabrication of integrated microring
resonators, requiring only one single epitaxial growth and two single-side
lithographic steps, is proposed in what is the simplest fabrication scheme
for vertical ...
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 ...
Induction theorem analysis of resonant nanoparticles: design of a huygens source nanoparticle laser
(American Physical Society, 2014)
info:eu-repo/semantics/article,
We propose an advanced formulation of standard antenna theory for the basic investigation and design of resonant nanoparticles. This methodology is based on transforming the original scattering problem into a radiation ...
Frozen mode from hybridized extraordinary transmission and Fabry-Perot resonances
(American Physical Society, 2013)
info:eu-repo/semantics/article,
Frozen modes arising in stacked subwavelength hole arrays are studied in detail. Their origin is proved to be connected with the interaction between the extraordinary transmission resonance and the Fabry–Perot cavity mode. ...
Wideband unidirectional transmission with tunable sign-switchable refraction and deflection in nonsymmetric structures
(American Physical Society, 2013)
info:eu-repo/semantics/article,
A general theory of reciprocal unidirectional transmission with tunable sign-switchable refraction and deflection of outgoing wave in structures with broken spatial inversion symmetry is presented. Several coupling scenarios ...
