    (University of Oum El Bouaghi, 2021) Ghalem, Salim; Lebbal, Mohamed Redha; Bouchemat, Mohamed
    In this work, we propose a photonic crystal fiber based on magneto-photonic crystal (MPC), formed by a triangular ring of circular air holes filled with magnetic fluid (MF) based on magnetic nanoparticle Fe3O4, in a Cerium substituted yttrium iron garnet medium (Ce -YIG), in this fiber, we have theoretically studied the conversion mode, reported and studied the effect of some parameters such as the radius and using a beam propagation method (BPM) in two dimensions. In our proposed structure the maximum conversion modes ratio equal to 98% with low coupling length Lc=15μm is obtained for gyrotropy g=0.35 and Faraday Rotation FR=1900 × 104 deg ∕cm.
