The main aim of this book is to introduce the concept of photonic information processing technologies to the graduate and post-graduate students, researchers, engineers and scientists. It is expected to give the readers an insight into the concepts of photonic techniques of processing as a system, the photonic devices as required components which are applied in the areas of communication, computation and intelligent pattern recognition.

Asit Kumar Datta is a former professor and ex-head of the Department of Applied Physics and later of the Department of Applied Optics and Photonics, University of Calcutta. He received his Ph.D. in power electronics from the University of Calcutta, and started his career at the same university as a lecturer. In 1989, he was appointed professor of the same department and later moved to the newly created department of Applied Optics and Photonics. Professor Datta has contributed significantly to the area of power electronics, control instrumentation, photonics, and optical computing. He executed 12 funded and sponsored research projects and has published more than 120 papers in national and international journals and conference proceedings, and he has also guided 14 research students towards their Ph.D. degrees. Professor Datta is a fellow of the Institution of Engineers, Institution of Electronics and Telecommunication Engineers, the Optical Society of India, and the Indian Society of Lighting Engineers. He represented India at the International Commission for Optics (ICO), Paris and was the Indian representative in two divisions of the International Commission of Illumination (CIE), Geneva.
Soumika Munshi received her M.Sc. (Tech.) degree followed by a Ph.D. in Applied Physics with a specialization in Optics and Optoelectronics from the University of Calcutta in 1996 and 2003, respectively.
