Low cost heat-and-pull rig for manufacturing adiabatic optical fiber tapers
Autor: Yamile Cardona Maya, Nelson Gómez Cardona, Pedro Ignacio Torres Trujillo
Publikováno v: Revista Facultad de Ingeniería Universidad de Antioquia, Iss 70 (2014)
In this paper we report the fabrication of adiabatic tapered optical fbers using a low cost heat-and-pull rig. Our setup is based on the flame-brushing technique moving in zigzag, where an inexpensive and simple portable gas micro-torch is used as h

Tunable Mode Converter Device Based on Photonic Crystal Fiber with a Thermo-Responsive Liquid Crystal Core
Autor: Pedro Ignacio Torres Trujillo, Esteban Gonzalez Valencia, Jorge Andres Montoya Cardona, Erick Reyes Vera, Nelson Dario Gomez Cardona
Publikováno v: Photonics
Volume 7
Issue 1
A compact tunable mode converter device based on the thermo-optically characteristics of liquid crystals (LCs) is proposed and numerically analyzed herein. The proposed mode converter consists of an asymmetric dual-core photonic crystal fiber (PCF) w

Analysis of photonic crystal fibers: Scalar solution and polarization correction
Autor: Pedro Ignacio Torres Trujillo, Francisco javier Velez hoyos, Victor Hugo Aristizabal Tique, Fernando José Da Silva Velez
Publikováno v: Optics express. 14(24)
A numerical approach based on the scalar finite element method is applied to analyse the modal properties of photonic crystal fibers having a solid core and a cladding region with either circular or non-circular microstructured holes. A correction wh

Modeling of photonic crystal fibers with the scalar finite element method
Autor: Pedro Ignacio Torres Trujillo, Francisco javier Velez hoyos, Victor Hugo Aristizabal Tique, Fernando José Da Silva Velez
Publikováno v: SPIE Proceedings.
A numerical model based on the scalar finite element method is applied to analyse the dispersion properties of photonic crystal fibers having a solid core and a cladding region with multiple air-holes. A correction which accounts for the polarization
