Unlocking the Future of 6G: A New Breakthrough in Terahertz Communication

Terahertz frequency electromagnetic waves hold significant promise for advancements in communication, as well as scanning and imaging technologies. However, harnessing their potential is fraught with obstacles. A team from Tohoku University has made a breakthrough by creating a new kind of adjustable filter specifically for the terahertz wave spectrum. Their findings were published in the journal Optics Letters.

Terahertz waves occupy a region of the electromagnetic spectrum between microwave and infrared frequencies. They have a higher frequency (shorter wavelength) than radio waves, but a lower frequency than visible light. The increasingly congested radio wave spectrum carries the vast amount of data transmitted by WiFi, Bluetooth, and current mobile phone (cellphone) communications systems.
