.Design of coating for broadband polarization — independent beam splitters and analysis of its optical performance[J].Optoelectronics Letters,2006,2(2):98-101 Design of coating for broadband polarization — independent beam splitters and analysis of its optical performance SHI Meng WU Fu-quan WANG Hai-long HAO Dian-zhong [1]Laser Research Institute, Qufu Normal University, Qufu 273165, China [2]Department of Physics, Guru Normal University, Guru 273165, China Abstract:       A design of coating on the entrance surface of the beam splitters with a transparent thin film of certain refractive index and thickness was presented. For this kind of beam splitters, it was possible to realize polarization-independent beam-splitting for chosen wavelength λ with incident angle ϕ. In addition, the simulation results using the coating designable software (Auto film) were consistent with the theoretical results, and the beam splitters are not sensitive to the small errors of film-thickness and film refractive-index over a broad spectra.
