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 ...
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 ...
Nanodeposition of materials with complex refractive index in long period fiber gratings
(IEEE, 2005) Artículo / Artikulua,
An overlay of higher refractive index than the cladding is deposited on a Long Period Fiber Grating (LPFG). This permits to improve in a great manner the sensitivity of the device to ambient and overlay refractive index ...
Deposition of an overlay with electrostactic self-assembly method in long period fiber gratings
(Optical Society of America, 2005) Artículo / Artikulua,
It was proved that the deposition of an overlay material onto a long-period fiber grating causes important shifts in the wavelengths of the typical attenuation bands that are caused by coupling between cladding and core ...
