Optical communication systems are increasingly displacing electronic methods because of their bandwidth, speed and reliability for long term usage. However, presently they suffer from the difficulty that all optical switching and routing are not possible on a microcircuit-sized scale, low values of the electro-optic coefficients, high cost of materials, complications in fabrication. As a solution to this problem organic polymers have been identified as a suitable material of choice in the optoelectronics area for device applications since, they offer flexibility in processing and properties and its simplicity has led to the possibilities of various futuristic Non-Linear Optical (NLO) device applications. For the design of organic materials suited for use in optoelectronic devices, Non-Linear Optical (NLO) chromophores incorporated in amorphous polymers based on the Host-Guest systems (here, 2-Methyl-4-Nitroaniline doped PES system) are subject to intense research activities. Such materials have numerous advantages as compared to the convectional crystalline materials.

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.
