We study modified optical vortices for encoding topological charges based on radius ratios between principal and the modified first sidelobe rings. The method is immune to harassments from alignment and phase matching between the beams and optical elements. Moreover, it is demonstrated that the radius ratios and their corresponding modulation parameters are independent to wavelength and size of the spiral phase mask.
