Deposition of an overlay with electrostactic self-assembly method in long period fiber gratings
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 ... -
Enhancement of sensitivity in long period fiber gratings with deposition of low refractive index materials
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 ... -
General synthesis of tapered matching sections for single mode operation using the coupled-mode theory
In this paper, a novel and general method to synthetize microwave waveguide tapers intended for single mode operation is proposed. The technique is based on the use of an exact series solution of the inverse scattering ... -
Influence in cladding mode distribution of overlay deposition on long-period fiber gratings
A thin overlay of higher refractive index than that of the cladding of a long-period fiber grating induces in cladding modes strong variations in effective index, mode profile, cross-coupling coefficient with the core ... -
