Photonic Bandgap Fiber for Infiltration-Free Refractive-Index Sensing

IEEE Journal of Selected Topics in Quantum Electronics, 2012
We report a novel photonic bandgap sensor, comprising a D-shaped fiber fabricated via side polishing. It takes advantage of measurand-elicited refractive-index profile changes upon exposure of its side-polished region to an ambient liquid. The bandgap shift can be induced by perturbations in close proximity to the fiber core, such as the change of ...

Highly-Sensitive Refractive Index Sensing by Near-infrared Metatronic Nanocircuits [PDF]

Scientific Reports, 2018
AbstractIn this work, we present a highly-sensitive refractive index sensor based on metatronic nanocircuits operating at near-infrared spectral range. The structure is designed based on simple nanorod geometry and fabricated by nanopatterning of transparent conducting oxides. The functionality of these polarization dependent metatronic nanocircuits is

A periodically coupled plasmon nanostructure for refractive index sensing

Optics Express, 2011
We present unique characteristics of subwavelength surface plasmon polaritons in a periodically coupled nanowell structure. The nanowell structure offers high quality internal surface plasmon resonance for sensing applications. Calculated FWHM of the transmission peak is 6 nm and the optical transmission is close to 100% at the resonant wavelength of ...
