Refractive Index is the fundamental parameter of the optical materials. Its variations with the wavelength/frequency are called dispersions. The variation of refractive index with temperature is called the thermo-optic coefficient. Similarly, the variation of refractive index with pressure is called the pressure-optic coefficient.

Gorachand Ghosh was a NEDO Fellow at the New Energy and Industrial Technology Development Organization from 1996 to 1999 and was an STA Fellow at the Electro Technical Laboratory (ETL), Tsukuba, Japan from 1993 to 1995, Japanese Government. He is the author or co-author of more than 80 publications in fields ranging from nonlinear optics to fiber optics, lasers, and condensed matter physics. Dr. Ghosh was a member of the Optical Society of America,the Australian Optical Society. He is a life fellow of the Indian Physical Society, and founding life member of the Indian Laser Association. He received his Ph.D. in nonlinear optics from Burdwan University, India in 1981. Since then he has taught and conducted research in the above fields in India, Australia, and Japan. His name has been nominated and listed in the Marquis Who's Who Publication, Who's Who in the World.

He is the author of the "Handbook of Thermo-Optic Coefficients of Optical Materials With Applications", published by the Academic Press of USA in 1997; Co-Editor of "The Electronic Handbook of Optical Constants of Solids" with Edward D. Palik published by the Academic Press of USA in 1999. Also, he is the author of the "Handbook of Refractive Index and Dispersion of Water for Scientists and Engineers", published by Sujata in 2005.
