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 ...
Long period fiber gratings with overlay of variable refractive index
(IEEE, 2005)
Artículo / Artikulua,
A theoretical analysis is presented of a long-period
fiber grating (LPFG) with an overlay of variable refractive index.
The highest sensitivity of the resonance wavelengths to variations
in the refractive index of the ...
