Rotation angle sensing via polarization-dependent mode superposition in a hollow-core fiber with two-fold symmetry
Enzo Dantas da Silva, Giovanna M. R. Castro, Murilo L. Batista +10
Hollow-core photonic crystal fibers (HCPCF) have experienced tremendous advancements recently, leading to remarkable demonstrations of transmission loss reduction and deeper unders…
In-series Multimode Interference Sensors and Fabry-Perot Interferometers for Enhanced Wavelength Shift Resolving Capabilities
João G. M. de Carvalho, Luiz D. C. Silva, Flavio A. M. Marques +10
We report on the development of a refractive index sensor obtained by using a singlemode-multimode-singlemode (SMS) structure and a Fabry-Perot interferometer (FPI) set into an in-…
Refractometry with filled antiresonant capillary fibers
Sinei Felix Gonçalves Junior, Lidia O. Rosa, Flavio A. M. Marques +5
We demonstrate the realization of refractometric measurements relying on the study of the transmission spectrum of filled capillary fibers. In this method, the fiber is filled with…
