Development Status of Terahertz in Australia OK or not?

Development Status of Terahertz in UK

The United Kingdom has established ThruVision, a company dedicated to the commercialization of THz imaging, which has developed passive THz imagers, and currently has commercialized passive THz imaging systems. TeraView, a high-tech company incubated by the University of Cambridge in the UK, is engaged in the development of THz cameras. The TPI Imaga 1000 and TPI Imaga 2000 three-dimensional imaging systems it has developed are the world's first commercial THz imaging systems used for the physicochemical properties of materials, and can be applied to non-destructive analysis and inspection. The EI company in the UK has produced THz gas lasers, and the Farran company in Ireland is also engaged in the development of THz sources and detector products. In addition, several companies based on the production of THz technology-related products have emerged in Germany, Switzerland, France, and other countries in recent years. In Asia, related companies are mainly concentrated in Japan and Korea. For example, Nikon Corporation in Japan has produced the YRayfact series of THz imaging systems; Murata Manufacturing has also developed new THz-related application products around THz technology; Fujitsu Limited in Japan has now begun researching THz lasers; United Microelectronics Corporation (UMC) in Taiwan has used its 0.13μm RFCMOS process technology to manufacture a push-push voltage-controlled oscillator with an oscillation frequency of 0.192 THz, setting a record for the highest oscillation frequency on a silicon chip (if using 65nm process, the oscillation frequency is expected to reach 0.35 to 0.4 THz). In summary, a new generation of IT industry based on THz technology has begun to gradually form, and the industrialization of THz technology will gradually enter the fields of industrial production, medical detection, environmental monitoring, safety inspections, and more in the future.

Development Status of Terahertz in Australia

In September 2024, an international team led by the University of Adelaide in Australia developed the first ultra-wideband integrated terahertz (THz) polarization multiplexer based on a substrate-free silicon platform and tested it in the Asia-Pacific THz J-band (220-330 GHz), which can be used for 6G and future communication technologies. The research findings were published in the latest issue of the journal "Laser & Photonics Reviews".

Terahertz prospects

The unique properties of terahertz (THz) have brought profound impacts to various fields such as communications (broadband communications), radar, electronic warfare, electromagnetic weapons, astronomy, medical imaging (label-free gene screening, cellular-level imaging), non-destructive testing, and security inspections (biochemical detection). Due to the high frequency of THz, it possesses a high spatial resolution; furthermore, its short pulses (in the picosecond range) result in a high temporal resolution.
