21st century is about convergence of Information technology, Biotechnology, Nanotechnology and Cognitive Technology. This remarkable convergence is based on the understanding of universe through basic sciences. Present day growth in Information and Communication Technology (ICT) has been possible only with breakthrough in electronics and microelectronics. The limitations associated with semiconducting materials for further miniaturization of electronic devices and limited bandwidth available for the information flow has led to innovations in using light as communication medium. This technology of light is called Photonics. [maxbutton id=”1″]
