Analysis of Long Period Gratings Inscribed by CO<sub>2</sub> Laser Irradiation and Estimation of the Refractive Index Modulation

Long period gratings (LPGs) inscribed in single mode fibers (SMFs) using CO<sub>2</sub> laser irradiation were modelled numerically using the coupled mode method. The model considers the specifications of the inscription technique, such as the shape of the refractive index modulation tha...
