Interference patterns at 60 nm wavelength produced by interfering the optical vortex beam with the reference beam without OAM. Left column: left circular polarization. Right column: right circular polarization. (a) Measurement results. (b) Same as (a) with the dotted curves representing the constructive interference patterns predicted by the theoretical model. The constant phase term of the theoretical model is adjusted to reproduce the measurements. (c) Simulation results by SRW code.
