Abstract Polarization dependency imposes great limitations for application of optical device in optical networks and systems. In this paper, we are going to design and propose a 1*2 all optical polarization independent power splitter based on photonic crystal structures. For designing such a device we should employ a fundamental photonic crystal structure which has joint photonic band gap. The obtained results show that at 1,560 nm wavelength the final structure has transmission efficiency equal to 45 % for outputs in both TE and TM modes.
