Biography
Dr. Pramod KUMAR now is a Photonics Research Fellow, Department of Physics and Astronomy, University of Exeter, England, United Kingdom. He has received his M. Phil. (Physics) degree from Indian Institute of Technology Roorkee (IIT-R), Roorkee, India in 2000, and the Ph.D. (Laser Physics) degree from Jawaharlal Nehru University (JNU), New Delhi, India in 2009. He has been worked as Assistant Professor at Delhi University, India in 2010. He has worked as Post-doctoral Research Associate (2011-2014) in Femtosecond Laser Laboratory, IISER Mohali, and Punjab, India. He has been with the University College Cork since Jan 2015, where he was the senior Laser research staff. His Research interest is in the field of ultrafast nonlinear Photonics with covers various fundamental and applicative aspects, in particular, the understanding, manipulation, and control of ultrashort pulses.

Optical Choas: Dynamical complexity of delay-coupled semiconductor Lasers system Mutually delay-coupled semiconductor lasers system show a plethora of dynamical complexity in the emitted radiation due to phase-amplitude coupling factor alpha, α that make them ideal candidate for fundamental studies of coupled oscillators as well as for practical applications ranging from optical communications to computing. On the one hand these dynamical instabilities are undesired features and disturb the many applications where one needs the constant stable high power but on the other hand, they may allow for new methods for secure communications using chaos synchronization. The variety of optical complexity in these systems which we have investigated theoretically as well as experimentally are well behaving, well understood, well classifiable in terms of complex nonlinear dynamics. So the systematic study and control of these nonlinear dynamics provide fundamental insight into the underlying physics of the system. On the basis of which one can redesign the device in order to stabilize the working point against environmental fluctuations or improve the processing, or simply exploit the dynamical performance of a system to one’s advantages.
