Dr Jayaprasath Elumalai


I received a Bachelor’s degree in Physics at the Loyola College (Madras University), Chennai, India, in 2008 and a Master’s in Physics from Pondicherry University, Pondicherry, India, in 2010.

In Sep 2011, I started to pursue my PhD Physics at the Department of Physics, Pondicherry University, India, under the supervision of Prof. S. Sivaprakasam. My PhD study was focused on the chaos synchronisation of diode lasers and propagation time delay influence in coupled complex systems. In October 2016, I obtained my PhD degree with a thesis titled ‘Intracavity propagation delay in synchronized chaotic semiconductor diode lasers.

During my PhD, I was awarded Junior Research Fellowship by University Grant Commission - Basic Scientific Research, Govt. of India from Dec 2014 to Sep 2015, and a Senior Research Fellowship by the Council of Scientific and Industry Research, Govt. of India from Oct 2015 to Aug 2016.

From Sep 2017 to Nov 2019, I carried out postdoctoral research with Southwest University, Chongqing, China, and carried out experimental work in vertical-cavity surface-emitting laser dynamics and microwave generation.

In Dec 2019, I moved to the UK as a postdoctoral research officer until Nov 2022 in the DSP Centre at Bangor University, Wales, where my research focused on physical layer secure optical transmission systems, networks of various topologies, and microwave photonics.

Research interests

I am a trained physicist specialising in the nonlinear dynamics of the diode laser. My research lies in the nonlinear dynamics of semiconductor lasers and their utilization for secure optical communications. 

I am actively working on locking and modulation schemes for quantum cascade lasers.
