Devices and Applications


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.
