Interesting you should mention the ISRO ITTR. The laser world of photonics is taking place in Bangalore. This is taken from Wikipedia:

“In June 1972 the Indian Space Research Organisation (ISRO) was established under the Department of Space and headquartered in the city. Bangalore also houses several research and development centres for many firms such as ABB, Airbus, Bosch, Boeing, GE, GM, Google, Liebherr-Aerospace, Microsoft, Mercedes-Benz, Nokia, Oracle, Philips, Shell, Toyota and Tyco.”

So Soma is in Bangalore, but not primarily for the conference......hmmm
