    Abstract:

Applications: The project proposes to develop a high-brightness triggered source of single photons and photon pairs, using laser cooled ensemble of Rubidium atoms coupled to two optical cavities.
Advantages: A cascaded four wave mixing scheme is proposed for optically pumped cold atoms to generate on demand photons together with a fast multi photon counting system to characterize the source. The key novelty of the project is implementation of a double cavity system integrated in conjunction with the atomic ensemble to enable operation at extremely low light levels. The two coupled optical cavities will be used to realize an on demand bi photon source, a still outstanding problem in the field. The high brightness photon source, once developed will be used, in conjunction with a confocal microscope to couple triggered photons to single nano particles, towards creating an interface between cold atoms and solid state materials.

THE VISION
THE MISSION
ABOUT I-STEM
It has always been the basic tenet of the Government of India, in generously funding R&D efforts at academic institutions over the years, that facilities established through such support be made available to those needing them and qualified to make use of them for their own research work

However, this was never easy or straightforward for, among other reasons, there was no ready source of information of what facility was available and where. Thanks to the Web, it is much easier today to have a national and regional “inventory of resources”, so as to match users with the resources they need, and to do all this in an efficient and transparent manner.

This can lead to a leap in R&D productivity and greatly enhance the effectiveness of public investment. This is the motivation behind I-STEM.
