Abstract

Wavefront characterization for orbital angular momentum (OAM) modes is demonstrated using quadrature phase-shift interference. The phase fronts and intensity profiles of OAM2, OAM4, OAM6, and OAM8 are measured. Wavefront correlations between the experimental results and the pure Laguerre–Gaussian modes are calculated to evaluate the measurement. The measured results are in reasonable agreement with the anticipated results based on simulations.
