Polypropylene-substrate-based SRR- and CSRR-metasurfaces for submillimeter waves
(Optical Society of America, 2008)
info:eu-repo/semantics/article,
In this paper it is presented the fabrication of low loss millimeter
wave metamaterials based on patterning on polypropylene substrates by
conventional contact photolitography. We study numerically and
experimentally ...
Planoconcave lens by negative refraction of stacked subwavelength hole arrays
(Optical Society of America, 2008)
info:eu-repo/semantics/article,
This work presents the design of a planoconcave parabolic
negative index metamaterial lens operating at millimeter wavelengths
fabricated by using stacked subwavelength hole arrays. A staircase
approximation to the ideal ...
Compact and highly-efficient polarization independent vertical resonant couplers for active-passive monolithic integration
(Optical Society of America, 2008)
info:eu-repo/semantics/article,
Compact low-loss polarization independent vertical coupling
between a 1.55 μm InGaAsP bulk active waveguide and a passive
waveguide based on bimodal interference is presented. Simulation results
show low coupling loss (<0.1 ...
Multi-tap complex-coefficient incoherent microwave photonic filters based on optical single-sideband modulation and narrow band optical filtering
(Optical Society of America, 2008)
info:eu-repo/semantics/article,
We propose a novel scheme to implement tunable multi-tap
complex coefficient filters based on optical single sideband modulation and
narrow band optical filtering. A four tap filter is experimentally
demonstrated to ...
Measurement of polarization dependent loss, polarization mode dispersion and group delay of optical components using swept optical single sideband modulated signals
(Optical Society of America, 2008)
info:eu-repo/semantics/article,
We introduce a novel method for high wavelength-resolution
measurement of polarization-averaged group delay, polarization dependent
loss and polarization mode dispersion of optical components using swept
optical single ...
Negative refraction in a prism made of stacked subwavelength hole arrays
(Optical Society of America, 2008)
info:eu-repo/semantics/article,
Metamaterial structures are artificial materials that show
unconventional electromagnetic properties such as negative refraction
index, perfect lenses, and invisibility. However, losses are one of the big
challenges to be ...
WDM bi-directional transmission over 35 km amplified fiber-optic bus network using Raman amplification for optical sensors
(Optical Society of America, 2005)
info:eu-repo/semantics/article,
We demonstrate a novel distributed fiber Raman amplified bus
topology used for WDM transmission over 35 km of single-mode fiber by
use of a multiwavelength Raman pump laser and eight Fiber Bragg gratings
(FBGs). This ...
Analysis of one-dimensional photonic band gap structures with a liquid crystal defect towards development of fiber-optic tunable wavelength filters
(Optical Society of America, 2003)
info:eu-repo/semantics/article,
A theoretical analysis of a fiber optical photonic band gap based
tunable wavelength filter is presented. The design presented here is based on
the quarter wave reflector with a liquid crystal defect layer in the middle ...
Comparison of wavelength-division-multiplexed distributed fiber Raman amplifier networks for sensors
(Optical Society of America, 2006)
info:eu-repo/semantics/article,
A novel distributed fiber Raman amplified star topology used for
optical sensor wavelength-division multiplexing is proposed. The
performance of this star configuration is compared to an optically amplified
bus topology. ...
Nanofilms on a hollow core fiber
(SPIE, 2006)
info:eu-repo/semantics/article,
We experimentally study the behavior of one multimode fiber–hollow core fiber–multimode fiber structure when nanofilms are deposited on it with the aim of developing practical evanescent field-based devices, such as sensors, ...
