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 ...
Ultra-compact planoconcave zoned metallic lens based on the fishnet metamaterial
(AIP Publishing, 2013)
Artículo / Artikulua,
A 1.5λ0 -thick planoconcave zoned lens based on the fishnet metamaterial is demonstrated experimentally at millimeter wavelengths. The zoning technique applied allows a volume reduction of 60% compared to a full fishnet ...
BOTDA measurements tolerant to non-local effects by using a phase-modulated probe wave and RF demodulation
(Optical Society of America, 2013)
Artículo / Artikulua,
We demonstrate a Brillouin optical time domain analysis sensor based on a phase modulated probe wave and RF demodulation that provides measurements tolerant to frequency dependent variations of the pump pulse power induced ...
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 ...
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 ...
Mode transition in complex refractive index coated single-mode–multimode–single-mode structure
(Optical Society of America, 2013)
Artículo / Artikulua,
By coating a single-mode–multimode–single-mode (SMS)
structure with a high refractive index thin-film it is possible to obtain a
transition of modes for specific combinations of thin-film thickness, thinfilm
refractive ...
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 ...
