BiFeO3 is multiferroic material with space group Pbnm exhibits coupling\nof both magnetic and electric orders under strain force. To analyze band gap\nTauc plot extrapolation method is used & remarkably smaller than some\nreported literature values for space group R3c structure. The dielectric\nfunction \ε(\ω) demonstrated that light energy upon transition\nthrough BiFeO3 has shown a decline inconsistent pattern with index of\nrefraction variation in range of 13 to 8, 8 to 5, 5 to 3, & 3 to 1 as per\nphoton energy. Moreover, non crossing degenerate energy level and hybridized\nspin-orbit interaction lead to linear dispersion relation which is typical\nphotonic nature with zero DM interaction. Thus, BiFeO3 could exhibit\nphotonic property under strain force. Generally strained structure had enhanced\nphotovoltaic effect with smaller optical band gap because of\nDzyaloshinskii-Moriya(DM) and spin-orbit coupling interactions.\n
