Simulations of OAM spectral shaper with Huygens-Fresnel principle. (A) The scheme of OAM spectral shaper. (B) Step-by-step field evolution of an initial superposed OAM state passing through the spectral shaper. (C) Initial OAM spectrum. (D) Output OAM spectrum. The brightness and color indicate the amplitude and phase distributions, respectively.
