Featured Profile

Lalitha Ponnampalam, Senior Research Fellow at the Department of Electronic and Electrical Engineering, University College London.

What research do you do?
My current interests include uncooled tuneable semiconductor lasers for low cost passive optical networks, photonic integration and wideband optical frequency comb generation for highly coherent millimetre wave/THz signal generation.

What brought you to University College London?
The Photonics Group at UCL has an excellent reputation in the design, fabrication and development of photonic devices and photonic integrated circuits (PICs) for communication systems, and has an outstanding laboratory facility with top-of-the-range equipment for PIC characterisation and system assessment. The group also has an impressive track record of participation in many EU/EPSRC funded projects in collaboration with other leading national and international institutions. These aspects, along with its central location in London attracted me the most.

What aspects of studying and conducting research in engineering do you like the most?
When we look at research in engineering, it is all about how we can use our technology to improve the world. It feels great when you know that what you are working on will have a positive impact in the society around you.
