Liquid level sensor based on dynamic Fabry–Perot interferometers in processed capillary fiber
(Springer Nature, 2021)
info:eu-repo/semantics/article,
In this work, a novel optical fiber sensor capable of measuring both the liquid level and its refractive
index is designed, manufactured and demonstrated through simulations and experimentally. For
this, a silica capillary ...
Single longitudinal mode lasers by using artificially controlled backscattering erbium doped fibers
(IEEE, 2021)
info:eu-repo/semantics/article,
In this work, we propose and experimentally demonstrate a new distributed short linear cavity fiber laser. At one of the cavity ends, fabricated by a commercial femtosecond fiber laser chirped pulse
amplfier, an artificially ...
Experimental assessment of first- and second-life electric vehicle batteries: performance, capacity dispersion, and aging
(IEEE, 2021)
info:eu-repo/semantics/article,
Nowadays, the reuse of electric vehicle batteries is considered to be a feasible alternative to recycling, as it allows them to benefit from their remaining energy capacity and to enlarge their lifetime. Stationary ...
Microdrilled tapers to enhance optical fiber lasers for sensing
(Nature Research, 2021)
info:eu-repo/semantics/article,
In this work, an experimental analysis of the performance of different types of quasi-randomly distributed reflectors inscribed into a single-mode fiber as a sensing mirror is presented. These artificially-controlled ...
Energy-efficient amplifiers based on quasi-floating gate techniques
(MDPI, 2021)
Artículo / Artikulua,
Energy efficiency is a key requirement in the design of amplifiers for modern wireless applications. The use of quasi-floating gate (QFG) transistors is a very convenient approach to achieve such energy efficiency. We ...
Silicon integrated subharmonic mixer on a photonic-crystal platform
(IEEE, 2021)
Artículo / Artikulua,
This paper presents a planar silicon integrated subharmonic mixer on top of a photonic-crystal platform. The local oscillator (LO) power is injected through a 2D photoniccrystal (PC) slab to a resonant cavity that effectively ...
Super-gain-boosted AB-AB fully differential Miller op-amp with 156dB open-loop gain and 174MV/V MHZ pF/uW figure of merit in 130nm CMOS technology
(IEEE, 2021)
Artículo / Artikulua,
A fully differential Miller op-amp with a composite input stage using resistive local common-mode feedback and regulated cascode transistors is presented here. High gain pseudo-differential auxiliary amplifiers are used ...
Hybrid Raman‑erbium random fiber laser with a half open cavity assisted by artificially controlled backscattering fiber refectors
(Springer Nature, 2021)
Artículo / Artikulua,
A hybrid Raman-erbium random fber laser with a half-open cavity assisted by chirped artifcially
controlled backscattering fber refectors is presented. A combination of a 2.4 km-long dispersion
compensating fber with two ...
Control design and stability analysis of power converters: the discrete generalized Bode criterion
(IEEE, 2021)
Artículo / Artikulua,
For the controller design and stability analysis of power electronic converters, the Bode stability
criterion and its subsequent revisions are the most practical tools. However, even though the control of the
power ...
Advances in fiber optic DNA-based sensors: a review
(IEEE, 2021)
info:eu-repo/semantics/article,
DNA is becoming increasingly important in the domain of optical fiber sensors, either as a tool for biosensing, or as a target to detect. In this review the main contributions of the last years are presented both in the ...
