Diseño de una rejilla inclinada de bragg basada en fibra óptica de dos modos para reducción del retardo modal

Abstract

The capacity of multimode fiber optic networks is greatly diminished by differential modal delay with increasing speed or distance. The article contributes to this line and proposes an inclined Bragg grating made on a two-mode optical fiber, which acts as a mode converter from LP11 to LP01, its optical and physical parameters were optimized, obtaining a 5 cm grating with an angle grid tilt θ_b=5 achieving a conversion intensity difference of 1000 times, which, when used as a modal filter, produces a differential modal delay compensation.
