Abstract :
In this work, a thorough numerical analysis of the impact of thermally-induced waveguide changes on the Single-Mode (SM) regime of the distributed modal filtering (DMF) photonic crystal fiber (PCF) has been performed by employing a full-vector modal solver based on the finite-element method, capable of taking into account the refractive index change on the fiber cross-section due to thermo-optic effect. Simulation results have been compared with those obtained for other rod-type fibers with a similar mode field diameter of about 65 μm.
