Bloch surface wave resonances generated with dielectric stack of high refractive index contrast deposited on a D-shaped optical fiber for sensing applications
Del Villar, Ignacio ; Kwietniewski, Norbert; González Valencia, Esteban; Burnat, Dariusz; Armas, Dayron; Pitula, Emil; Matías Maestro, Ignacio ; Chiavaioli, Francesco; Torres, Pedro; Smietana, Mateusz (Optica Publishing Group, 2022) Contribución a congreso / Biltzarrerako ekarpenaA 5-layer stack composed of TiO2 and Al2O3, two materials with a high refractive index contrast, was deposited on a D-shaped fiber to generate Bloch surface wave resonances with an improved figure of merit. -
Bloch waves at the surface of a single-layer coating D-shaped photonic crystal fiber
González Valencia, Esteban; Del Villar, Ignacio ; Torres, Pedro (Optical Society of America, 2020) Artículo / ArtikuluaBloch surface wave (BSW) platforms are particularly interesting for light confinement and surface sensitivity, as an alternative to the metal-based surface plasmon polaritons (SPP). However, most of the reported BSW platforms ... -
Novel bloch wave excitation platform based on few-layer photonic crystal deposited on D-shaped optical fiber
González Valencia, Esteban; Del Villar, Ignacio ; Torres, Pedro (Nature Research, 2021) Artículo / ArtikuluaWith the goal of ultimate control over the light propagation, photonic crystals currently represent the primary building blocks for novel nanophotonic devices. Bloch surface waves (BSWs) in periodic dielectric multilayer ... -
Side-polished photonic crystal fiber sensor with ultra-high figure of merit based on Bloch-like surface wave resonance
González Valencia, Esteban; Reyes-Vera, Erick; Del Villar, Ignacio ; Torres, Pedro (Elsevier, 2024) Artículo / ArtikuluaA Bloch surface wave (BSW) resonance configuration is introduced for biosensing with an ultra-high figure of merit (FOM). The BSW excitation is realized through the evanescent field of the core-guided fundamental mode of ...
