Fiber-optic nanorefractometer based on one-dimensional photonic-bandgap structures with two defects
(IEEE, 2004) Artículo / Artikulua,
A theoretical analysis of a fiber-optic photonic- bandgap (PBG)-based nanorefractometer is presented. Changes up to 11.2 dB in the optical output power in an index of refraction range of 1.7 with a sensitivity of 1.5 ...
Spectral evolution with incremental nanocoating of long period fiber gratings
(Optical Society of America, 2006) Artículo / Artikulua,
The incremental deposition of a thin overlay on the cladding of a long-period fiber grating (LPFG) induces important resonance wavelength shifts in the transmission spectrum. The phenomenon is proved theoretically with ...
Generation of selective fringes with cascaded long-period gratings
(IEEE, 2006) Artículo / Artikulua,
The inscription of cascaded long-period gratings of different periods in optical fiber permits us to obtain both narrowband and wideband filters in the same spectrum. If used as an optical transducer, it may permit us ...
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 ...
Optimization of sensitivity in long period fiber gratings with overlay deposition
(Optical Society of America, 2005) info:eu-repo/semantics/article,
The deposition of an overlay of higher refractive index than the cladding in a Long Period Fiber Grating (LPFG) permits to improve the sensitivity to ambient refractive index changes in a great manner. When the overlay is ...
