RE: The future of wireless communication hinges on Terahertz frequencies
This is realy nice article, and effort.
However, for communication system terahertz sources are used right now. For example, for telecom applications, they are using 1550nm light which is equals order of ten THz. Although 1550nm wavelength source are improved, they have lots of problems such as fiber issues problem (SRS, SBS, etc.). If they will use this kind of source in the free space, it is also problematic. Because the light has a disadvantes about transmission on a dirty air. LiFi is the one of the application for free space communication. Also there is an another issue about transmission inside the fiber is that, right now, we are so limited to about source range. For example there are some wavelengths 800 nm 1000nm 1550nm or 2000nm which are the compatible with the transmission with the fibers. In future it can be developed for other wavelengths but right now we are so limited thz source.
Also i cannot get the idea of thz source to detection, how they make do you have an idea? How the thz source passing through our clothes materials?
Thanks again to post this review..
Thanks for reading and sharing your insight on terahertz and fibre optics @onderkcaalan. And i did mention that this is going to be futuristic, in the sense that research on its benefits and its application are still ongoing. About SBS, i agree that it could be an issue with fiber optics, because it usually occurs when the amount of light being passed into the fibre exceeds the power level threshold suited for the launch and transmission process. However, this won't be much of an issue, as the researchers are still working to ensure the application of Terahertz is seemlessly achieved in telecom. The potential of speed which it boasts of, and the radiation free wavelength transmission, would definitely make it a choice of the future; as the present day gigahertz, would eventually be unable to sustain our need and demand for faster speed of transmission of data in the no-distant future.
