en عمومى General كاربردي Applicable <p style="text-align: justify;">In this paper, a Y-shaped power splitter based on a two dimensional photonic crystal (PhC) for TE modes is designed and optimized. A triangular lattice of air holes is used for Y-shaped power divider. For analyzing these structures, plane wave expansion (PWE) and finite difference time domain (FDTD) methods are used. The simulation results show that more than 98% of the input power is transmitted to the outputs and the structure has just less than 2% reflected power. According to the simulation results this structure is suitable for high bandwidth optical integrated circuit at the 1550 nm wavelength.</p> <p style="text-align: justify;"></p> power splitter, photonic crystal, FDTD, Y-junction, optical power divider. 33 42 http://ijop.ir/browse.php?a_code=A-10-549-1&slc_lang=en&sid=1 Mohammad Danaie danaie@semnan.ac.ir 10031947532846002112 10031947532846002112 Yes Semnan University Ruhollah Nasiri Far ru.nasirifar@semnan.ac.ir 10031947532846002113 10031947532846002113 No Semnan University Abbas Dideban 10031947532846002114 10031947532846002114 No Semnan University
