UCLA Integrated Sensor Laboratory Breaks Barriers in High-Speed Wireless Communication with THz Technology
LOS ANGELES (PRWEB) June 14, 2023 -- The THz band, spanning from 0.3 to 3 THz, holds immense potential for sensing and high-speed communication applications. However, until now, this band has remained largely untapped due to the challenges in signal generation. The Integrated Sensor Laboratory at UCLA has developed cutting-edge technology for THz generation by leveraging the charge storage limitations in integrated silicon diodes.
This pioneering technique has resulted in unprecedented results from the UCLA-ISL lab, including the world’s first implementation of a multi-Gbps wireless transceiver above 300 GHz, the most efficient silicon-based THz generation at 0.4 THz, and 0.4-4 THz signal generator extending into the far-infrared region. These advancements will be showcased at the upcoming IEEE Radio Frequency Integrated Circuits Conference in San Diego this June.
The introduction of the new multi-Gbps wireless THz transceiver by the UCLA-ISL lab marks a milestone on the path to 6G technology, offering low-latency, high-throughput computing capabilities. The THz transceiver, which is fabricated in Global Foundries process, provides an impressive 10Gbps over-the-air link at 5cm and 5 Gbps at 20 cm, all without the need for collimating lenses or expensive machined waveguide modules. The energy per bit for transmitting data is 53pJ/bit, which is about half of the existing fully integrated THz transceiver technologies. This reduction in energy consumption is of utmost importance for high-performance computing systems, as the energy utilized for data transfer largely dominates their power consumption. Consequently, this breakthrough holds immense potential for emerging applications such as augmented reality/virtual reality (AR/VR), generative AI, and many more.
