Hello Varun,
In IIT Delhi's engineering physics programme, focus on nanotechnology and photonics, both emerging technologies. They use equipment like LASERs and create thin films, with a thickness of ~100 nanometers. They study physics, in both, its purest form, as well as when applied, and take on the universe, trying to harness the secrets it holds for the betterment of human lives.It is more of a theoretical and research based branch, if you have a keen interest in physics, you can surely go for it.
