Tektronix, a global level measurement solutions provider, recently spoke about its potential to back futuristic ultra-high bandwidth wireless communication links considering the significant role its instruments are playing in technology demonstration. According to an article published in a journal, an international level team reported one of the first transmission of two real-time video signals via a terahertz multiplexer at an approximate data rate of 50 Gbps which is 100x faster as compared to cellular network.
As the demand for data transmission speeds and capacities is expanding beyond the present day microwaves potential, search for new ways to make use of higher frequency THz waves with much larger capacity to carry out data and information. A team formed by an international collaboration between the Institut d’Electronique de Microelectronique et de Nanotechnologie (IEMN) and Brown University. This team has already proved that the radio and fiber optics domain can be easily bridged with the help of photonic based THz circuits for achieving higher data rates. Nevertheless, if any system needs to be viable a system for demultiplexing and multiplexing signal is one of the basic needs. They made use of a waveguide system with two metal plates in a parallel way, the researchers then encoded two high-definition TV broadcasts over terahertz waves of two different frequencies – 322.5 GHz and 264.7 GHz. these two frequencies were then sent together in a multiplexer system, the television receiver set was able to detect those signals that emitted from device. Other experiments also showed how this system could deliver data rates up to 50 Gbps with lower error rates.
Guillaume Ducournau, an assistant professor from IEMN adds that, “What this demonstration definitely showed is that a THz multiplexing system can be used to carry actual data without the streams interfering with each other. With support from Tektronix, we were able to fully test and characterize our system and the results show that this approach could lead to future commercial application of THz wireless networks.”
