Phasorial differential pulse-width pair technique for long-range Brillouin optical time-domain analysis sensors
(Optical Society of America, 2014)
Artículo / Artikulua,
We introduce a novel phasorial differential pulse width pair (PDPP) method for Brillouin optical time domain analysis (BOTDA) sensors that combines spatial resolution enhancement with increased tolerance to non local ...
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 ...
Refractometric sensors based on multimode interference in a thin-film coated singlemode– multimode–single-mode structure with reflection configuration
(Optical Society of America, 2014)
Artículo / Artikulua,
Thin-film coated single-mode–multimode–single-mode (SMS) structures have been analyzed both theoretically
and experimentally with the aim of detecting different refractive indices. By adequate selection
of the thickness ...
Second-order nonlocal effects mitigation in Brillouin optical time-domain analysis sensors by tracking the Brillouin frequency shift profile of the fiber
(IEEE, 2017)
Artículo / Artikulua,
We report on an additional limitation that has been found in Brillouin optical time-domain analysis (BOTDA) sensors due to the so-called second-order nonlocal effects (NLE). Second-order NLE appear in BOTDA setups that ...
46-km-long Raman amplified hybrid double-bus network with point and distributed Brillouin sensors
(IEEE, 2012)
info:eu-repo/semantics/article,
We experimentally demonstrate a 46-km hybrid network that combine point and distributed Brillouin sensors. The proposed sensor network multiplexes low-cost intensity point sensors based on fiber-optic tapers, which are ...
