摘要：
We present the design and experimental results of channel multiplexing using orbital angular momentum (vortex beams) at 0.14 THz. A 3D printed spiral and porous phase masks are used to generate vortex beam of order m=+1 and m=-1 for channel 1 and 2 multiplexing and the inverse phase masks (m=-1 and m=+1) is used for demultiplexing. The phase masks are validated by measuring the output amplitude and phase using the THz time domain system. We will also demonstrate and compare the bit error rate of spiral and porous phase masks in each communication channel.
