Wealth when shared gets divided; knowledge when shared gets multiplied. Seminars are one of these knowledge multiplying platforms as they spread awareness on topics beyond our syllabus and I was fortunate enough to attend two such sessions that made me wonder about the amazing advancements in science.
The first session, delivered by Dr. Reji Philip, truly blew my mind away. He is currently employed as a professor at Light & Matter Physics Group, Raman Research Institute and has specialized in nonlinear optics. Acquiring his post-doctoral training from University of Regensburg in Germany, he has reviewed several international journals and held visiting scientist positions at the University of Massachusetts, Boston, USA, and University of Central Florida, Orlando, USA. He’s a human encyclopedia on lasers. The workshop provided an insight in the fundamentals of a simple laser, in layman terms. Attractive demonstrations and vivid videos made the session even more interesting. It was fascinating to learn that Albert Einstein first suggested the idea of a laser, which intrigued people to create masers (primitive lasers). Above all, the entire physics and mechanics marking the existence of the laser are captivating.
The second session was based on the applications of the first, optical communications to be precise. It was presented by Dr. Srinivas Talabattula, an associate professor in the ECE Department, Indian Institute of Science, Bangalore. He was a post-doctoral fellow at Toyohashi University of Technology, Japan. His engaging persona acted as a catalyst in transferring information effectively. Transmission of data through light is called optical communication. The seminar helped in understanding the basic phenomenon behind the working of optical fibers. The benefits of optical fibers over conventional media are huge; they are light, fast and eco-friendly. Surgeries using light to correct defects in the human body are medical marvels and thus, optics altogether is the backbone of the modern world.
