We present an extensive study of an ultra-compact grating-based beam splitter suitable for photonic integrated circuits (PICs) which have stringent density requirements. In this paper, we propose a one-dimensional polarization beam splitting grating under normal incidence with excellent polarization characteristics and a high diffraction efficiency. The main structure is a double-groove slanted grating. The 10 m long beam splitter exhibits equal splitting, low insertion loss, and also provides a high extinction ratio in an. In this work, a reflective beam-splitter based on a metallic Ronchi diffraction grating normally illuminated is designed and analysed. The GIRO grating is a simple binary diffraction grating with parameters chosen such that the excited optical modes in the grating interfere constructively and destructively at the respective. These gratings can obtain a high polarization extinction ratio with an appropriate set of parameters of grating structures and the incidence angle. The polarization beam splitters with different operating modes (trans-reflective) was designed, and the finite-difference time-domain (FDTD) method was.
