Hi Reddit, I am Paramita Pal, researcher at the University of Bath. My research focuses on improving signals for the future mobile communications. I create optical fibres for high-speed internet and other mobile communications. It sounds serious, ...
I joined the University of Bath in January 2023. During my Ph.D., I worked with ultrafast lasers with pulse duration in the range of femtosecond (1 quadrillionth of a second) to improve light amplification in materials/optical fibres that we use for internet and other communications.
Although the work seems intense and difficult, it is exciting. I spend long hours in the lab making useful materials to achieve faster internet. Using glass capillaries of different diameters and following our designs, we can prepare fibres using our fibre facility in a two-stage process. These are known as hollow core fibres and have advantages over regular fibres.
When the fibre is filled up with vapour using some equipment at the University of Bath, it will be used for the next generation of mobile communications. This would be huge impact for our day-to-day lives as we are living in the era where lots of data traffic occurs. These new fibres could allow us to download videos or stream faster than we could imagine!
I would like to answer and explain the questions on the fibre-optics, ultrafast lasers, how the fabrication works and how we are going to improve data transmission, please Ask Me Anything!
I’ll be online to answer questions on Wednesday 4 October, 2.30 - 3.30pm BST.
