This work presents the simulation design of a hexagonal Photonic Crystal Fiber (PCF) laser tailored for optical communication applications. Utilizing the Finite Element Method through COMSOL Multiphysics (6.1) simulation software, to study the optical characteristics of the proposed PCF structure, including effective refractive index (neff), confinement loss (Lc), effective mode area (Aeff), nonlinear coefficient (γ), and dispersion. The influence of infiltrating the PCF air holes with varying refractive indices (1.0, 1.33, 1.354, 1.37, and 1.39) on laser performance was systematically analyzed. The results demonstrate a Gaussian-shaped laser output with stable intensity profiles over a wavelength range of 1200 nm to 2000 nm. This wide operational bandwidth and the tunable design make the proposed PCF laser a promising candidate for advanced optical communication systems.
