Dr. S. Sivaprakasam
About
Research Area
Graduated from University of Hyderabad, Post-Doctoral research was in the field of experimental quantum electronics at Bangor University, UK. This research had its first demonstration of synchronization and its variants using chaotic diode lasers. This team work was recognized by SET – 2000 Award by the House of Commons, London. The field of chaos synchronization of time-delayed systems is the necessary precursor for futuristic secure optical communication. Numerical simulations of experiments constitute current core research.
