Journal ArticleDOI
Ultrahigh-sensitivity temperature fiber sensor based on multimode interference
Susana Silva,Edwin G. P. Pachon,Marcos A. R. Franco,Juliano G. Hayashi,F. Xavier Malcata,Orlando Frazão,Pedro A. S. Jorge,Cristiano M. B. Cordeiro +7 more
TL;DR: The proposed sensing device relies on the self-imaging effect that occurs in a pure silica multimode fiber (coreless MMF) section of a single-mode-multimode-single-mode (SMS)-based fiber structure to extend the range of liquids with a detectable RI to above 1.43.
Journal ArticleDOI
Surface-enhanced Resonance Raman Scattering (serrs) Using Au Nanohole Arrays On Optical Fiber Tips
Gustavo F. S. Andrade,Gustavo F. S. Andrade,Juliano G. Hayashi,Mohammad M. Rahman,Walter J. Salcedo,Cristiano M. B. Cordeiro,Alexandre G. Brolo +6 more
TL;DR: In this article, the effect of the hole shape on the surface-enhanced resonance Raman scattering (SERRS) performance was explored with the bow tie nanostructures presenting a better SERRS performance than the circular holes arrays.
Journal ArticleDOI
Photonic-crystal fiber-based pressure sensor for dual environment monitoring
Jonas H. Osório,Juliano G. Hayashi,Yovanny A. V. Espinel,Marcos A. R. Franco,Miguel V. Andrés,Cristiano M. B. Cordeiro +5 more
TL;DR: The development of a side-hole photonic-crystal fiber (SH-PCF) pressure sensor for dual environment monitoring is reported and properties (phase and group birefringence, sensitivity to pressure variations) are measured and compared to simulated data.
Journal ArticleDOI
Fiber-Drawn Metamaterial for THz Waveguiding and Imaging
Shaghik Atakaramians,Alessio Stefani,Alessio Stefani,Haisu Li,Haisu Li,Md. Samiul Habib,Juliano G. Hayashi,Alessandro Tuniz,Xiaoli Tang,Jessienta Anthony,Richard Lwin,Alexander Argyros,Simon Fleming,Boris T. Kuhlmey +13 more
TL;DR: In this paper, the authors discuss the fabrication technique and the structures that can be obtained before focusing on two particular applications of terahertz metamaterials, i.e., waveguiding and sub-diffraction imaging.
Journal ArticleDOI
Pressure Sensing Based on Nonconventional Air-Guiding Transmission Windows in Hollow-Core Photonic Crystal Fibers
TL;DR: In this article, the authors identify non-conventional core-guided transmission windows within the visible spectral range in commercial hollow-core photonic crystal fibers designed to operate at 1550 nm.
