INTRODUCTION
In
this computer world, optics plays a vital role in processing the information
from one place to another. This leads to the design of opto (light)-electronic
(electrons) devices which process the information faster, accurate and at low
cost, consuming less space.
The
interaction between electrons and photons in a material is the basis of all
opto-electronic devices.
Thus,
optical materials are the materials in which the conductivity is increased due
to photons falling on it. They are used in opto-electronic devices such as
cathode ray tube (CRT), light emitting diode (LED), liquid crystal display
(LCD), LASER, Quantum dot laser, Photo detectors, computers, calculators etc..
The optical properties of the materials makes us to understand the interaction
between the electrons and photons.
