Enhancement of sensitivity in long period fiber gratings with deposition of low refractive index materials
(Optical Society of America, 2005)
Artículo / Artikulua,
It was proved [Opt. Lett. 30, 720 (2005)] that the deposition of an overlay of higher refractive index than
that of the cladding on a long-period fiber grating (LPFG) causes large shifts in the attenuation bands induced
by ...
Development of an optical refractometer by analysis of one-dimensional photonic bandgap structures with defects
(Optical Society of America, 2003)
Artículo / Artikulua,
A theoretical analysis of an optical fiber photonic-bandgap-based refractometer is presented. The design is based on a quarter-wave ref lector with one defect. By modifying both the real and the imaginary parts of the index ...
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 ...
