We present a novel technique for manufacturing a long‐period fiber grating (LPFG) with enhanced torsion sensitivity based on electric arc technique. The proposed method rotates the fiber around its axis of rotation at each electric arc discharge. We experimentally investigated the torsion‐dependent spectral response of the produced grating and the results showed that an enhanced linear torsion sensitivity up to 0.197 nm/(rad/m) was achieved, which is higher than that of the conventional arc‐induced LPFGs.
O presente trabalho investiga o impacto da dispersão por modos de polarização (PMD) em uma fibra óptica compensadora de dispersão (DCF). Vale ressaltar que este fenomeno é um fator limitante nos sistemas de alta capacidade ainda pouco explorado e, por ser de natureza aleatória, difículta sua determinação.Desta forma, torna-se necessário recorrer a modelos estastísticos. Foram utilizados dois métodos de medidas da PMD: O primeiro baseado na técnica interferométrica no domínio temporal e o segundo na técnica polarimétrica no domínio da frequência.
