Abstract:Because of the special diffraction characteristic of sub-wavelength grating structures, light energy with different polarization states will distribute in different diffraction orders. 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 (reflective) was designed, and the finite-difference time-domain (FDTD) method was used to simulate the intensity of ea… Show more
