OPTHER(Optically Driven Terahertz Amplifiers) is a
project that has the aim to develop new vacuum devices for
amplification of T-rays (Terahertz frequencies). These devices will
make possible sophisticated applications with a huge potential in
different fields such as aerospace, security, medical applications,
diagnostics for art conservation. It is well known in fact that there is
for THz radiation, the lack of compact, cheap, powerful and efficient
This project undertakes to overcome those limiting factors by solving
the power/size limitation of THz sources innovatively combining
available optical THz sources (such as Quantum Cascade Lasers (QCL) or
photo mixing systems) and developing a compact, efficient and reliable
novel vacuum THz amplifier to boost the overall performance.
Micromachining and nanotechnologies are extensively applied in the novel
THz amplifier design and realization in terms of field emitting carbon
nanotubes (CNT) used as cold cathodes and interaction structures working
in the THz region.
OPTHER is a 3 year project (1st April 2008 - 31st
March 2011) funded by the European Union for a total of 2,449,847 euros
for three years. The overall cost of the project is 4,100,285 Euros.
The partners involved in the project are : University Rome "Tor Vergata", coordinator of the project -ITaly , the Technical University of Denmark, the National Center for Scientific Research (CNRS) - France, SELEX-Integrated Systems - Italy, Thales Research & Technologies and Thales Electron Devices - France.
