Opto-Microwave and Metamaterial Research Laboratory

 

Contact Person: Prof. Subal Kar

Research Activities in The Lab: Modified resonant-cap IMPATT Oscillators, Amplifiers, and Twin-cap IMPATT Power Combiners have been developed in this lab at microwave frequency and three patents have been granted for these innovative developments.

Plasmonic metamaterial has been developed in this lab First Time in India in collaboration with SAMEER, Kolkata and Reactor Control Division of BARC, Mumbai. A news item regarding this success has been reported in Nature (India Section): [http://www.nature.com/nindia/2009/090820/full/nindia.2009.273.html] dated 20th August 2009. Further research is going on for the development of metamaterial based passive components like phase shifter, couplers etc.

A collaborative research with Lawrence Berkeley National laboratory, University of California at Berkeley, U.S.A is going on for the development of “Timing and Synchronization” system for LUX (Laser-based Ultra-fast X-ray source) useful for nano-scale diagnostics cutting across all branches of Science. The generation of ultra-stable microwave and millimetre-wave signal required for this project is under development in this laboratory using optical down-conversion from laser sources.
