Terahertz electronics for spectroscopy and imaging has become a major new research area.
Applications in security screening, biomedical analysis (e.g. tumor detection) as well as non-destructive testing in production processes (e.g. plastics, foams, paint) are emerging.
Along with the discovery of new applications, the realization of miniaturized and cost-effective spectroscopy and imaging systems is a challenge.
The research area “Terahertz Electronics for imaging and spectroscopy” consists of two research lines:
- CMOS integration of imaging and spectroscopy systems:
The extreme high frequencies, which are typically above the fT and fmax of the most advanced CMOS processes, require new approaches for the generation and detection of such signals.
Research in this line investigates methods to push the frequency and power limits based on up- and down-conversion mixers, as well as on transmitter and receiver arrays. A system approach is taken in order to reach systems that are useful for specific applications.
- Application research:
In order to justify the investment into system integration, application demonstration is required. Companies as well as new research initiatives require a better understanding about the feasibility as well as specifications for new applications in the sub-terahertz frequency domain. Therefore this research line builds imaging and spectroscopy setups based on commercially available equipment, that allow testing of new applications.
Currently spectroscopic imaging of amplitude and phase up to 370 GHz is available and is used for various collaborations with other partners inside and outside TU/e.
