Teratronic Signal Processing

The Teratronic Signal Processing Group specializes in pushing the technological limits of the on-chip signal processing into the Tbit/s regime using high-speed plasmonic modulators and detectors which exploit the high non-linearity and fast response of electro-optic polymers. The group develops devices with cutting-edge technology with its state-of-the-art fabrication facilities available on campus.

The wireless link bridges a broad river in difficult-to-access terrain to provide high-speed internet access in remote and rural areas

There is an increasing thrust to boost the capacity of fiber-optic links, which at the moment run at a maximum speed of 40 Gbit/s. Entering into desirable terabit data rates calls for a new generation of devices – modulators, detectors and high speed electronics to process the data. Apart from research on Silicon-Organic-Hybrid (SOH) modulators, the group explores new disruptive technologies to tackle the problem.
The THz frequency range (0.1 – 10 THz), commonly referred to as the "THz gap" has been inaccessible for communication systems for quite some time due to the lack of efficient sources at these frequencies.  Given the current scenario, the research activities of the group can be classified into three categories:  (1) THz generation – where new efficient THz generation techniques using different non-linear materials are explored, (2) THz modulation – ultrafast low foot-print modulators based on plasmonics are tested in the THz regime (3) THz detection – in-house fabricated ultrafast detectors based on optical heterodyne mixing are explored.
