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 ...
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 ...
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. ...
Frequency modulated continuous wave system for optical fiber intensity sensors with optical amplification
(IEEE, 2009)
info:eu-repo/semantics/article,
We report on the use of erbium doped fiber (EDF) amplification to enhance a frequency modulated continuous wave (FMCW) technique for referencing optical intensity sensors located between two Bragg grating structures. The ...
Stability comparison of two ring resonator structures for multiwavelength fiber lasers using highly doped Er-fibers
(IEEE / OSA, 2009)
info:eu-repo/semantics/article,
An experimental comparison of stability between two different fiber laser topologies is carried out. The lasers are based on ring resonators that include highly-doped Er-fibers. Both topologies use fiber Bragg grating ...
Resilient amplified double ring optical networks to multiplex optical fibre sensors
(IEEE / OSA, 2009)
info:eu-repo/semantics/article,
We report the experimental demonstration of two configurations of an amplified optical fibre double ring network for the multiplexing of sensors. The networks are designed to be inherently resilient to fibre failures because ...
Experimental evidence of coherence resonance in a time-delayed bistable system
(APS Physics, 2007)
info:eu-repo/semantics/article,
We report on the experimental observation of coherence resonance in a bistable system with delay. Our system consists of a vertical-cavity surface-emitting laser subject to time-delayed optical feedback
simultaneously from ...
Polarized optical feedback from an extremely short external cavity for controlling and stabilizing the polarization of vertical cavity surface emitting lasers
