Correction of phase distortion of an OAM mode using GS algorithm based phase retrieval

The Gerchberg-Saxton algorithm based phase retrieval technique is used to correct the wavefront of distorted OAM modes. The simulation results show that this method can efficiently improve the mode purity of OAM modes up to 50% and reduce the crosstalk by about 20 dB.
