Research Area

After graduating from University of Hyderabad, my post-doctoral research was in the field of experimental quantum electronics at Bangor University, UK. This research had its first reporting of synchronization, inverse synchronization, cascading and anticipating synchronization using various combinations of two or mode chaotic diode lasers. The combinatory work of the team was recognized by a Parliamentary in the year 2000 (SET – 2000) by the House of Commons, London. The field of chaos synchronization forms the basis for secure optical communication, which is seen as the natural successor for existing electronic encryption of information.
