Sensitive Orbital Angular Momentum (OAM) Monitoring by Using Gradually Changing-Period Phase Grating in OAM-Multiplexing Optical Communication Systems
We propose specially designed gradually changing-period phase grating (GCPPG) and used it to monitor the orbital angular momentum (OAM) light beam. Based on GCPPG, zero-order diffraction can be eliminated, and the diffraction power can be concentrated to the first-order diffraction. In this way, the...
