CST Global shares iBROW and WiPHi project findings at the UoG, THz Electronics Workshop


28 June 2018

Terahertz (THz) technology is currently breaking into many major application fields, such as wireless, medical, non-destructive materials testing, radar, security, food processing and space. The THz Electronics Workshop, at the University of Glasgow, shares research findings and discusses current and future trends in THz electronics. It is chaired by Dr. Edward Wasige, High Frequency Electronics Group Leader at the University of Glasgow.

The most recent THz Electronics Workshop was attended by over 100 scientists and engineers from across Europe. It provided the ideal platform for presenting the findings of two, current, wireless-over-fibre projects; iBROW and WiPHi. Both projects are collaborations between CST Global and the University of Glasgow and both are managed by Dr. Horacio Cantu, Research Engineer at CST Global (pictured) and Dr. Edward Wasige at the university.

Horacio explains:

iBROW is an EU-funded, Horizon 2020 project, completing in June 2018. It has helped establish optimal, wireless, mm-wave carrier frequencies for high speed communications using between 84GHz and 300GHz. It has also investigated wireless baseband to optical domain conversion at wavelengths of 1270, 1310 and 1550nm. The baseband data-rates investigated were 10Gbps and above.

WiPHi is a UK government-funded, Innovate UK project, running from January to December 2018. It has an additional commercial partner, Optocap Ltd. The WiPHi project is focused on 60GHz wireless transmission and baseband conversion for optical domain networks using RTD-LD (Resonant Tunneling Diode-Laser Diode) drivers, which include DFB lasers made by CST Global. In this project, we are investigating 1310nm and 1550nm wavelengths for indoor communications, using the existing, V-band communications framework. The data-rate possible with the WiPHi technology is around 7Gbps, with low-latency; increased transmission speed; immunity from interference; enhanced security; and a reduction in component count and antenna size.

Eminent academic speakers at the THz Electronics Workshop included Prof. Elliott R. Brown from Wright State University, USA; Prof. Imran Mehdi from JPL-NASA, USA; Prof. Masahiro Asada from Tokyo Institute of Technology, Japan; and Prof. Tadao Nagatsuma from Osaka University, Japan.
