MIMO Systems for 6G THz Data Transmission Links

The recent advancements in terahertz (THz) physics drive the development of 6 G technology. Multiplexing THz signals into a single optical path represents a highly promising technique for enhancing the data capacity of forthcoming data links. This study introduces the concept of applying two different diffractive elements to combine THz beams into a single communication channel, subsequently separating them for detection. These elements have been designed, optimized, simulated, manufactured and experimentally validated.
