An experimental setup is built to realize 8-bits information transmission based on orbital angular momentum (OAM) of light beams. In the modulation section, a controllable laser diode array and a stable phase modulator are used to superpose and encode the OAM states. A binary amplitude grating is used to detect the OAM states in the demodulation part. This system transmits 8-bits data successfully.
