| Optical fiber is now the backbone of present days’ telecommunications network. The basic fiber material is high
purity silica glass. Most of the technologies are now perfected and research is now directed towards new highly
transparent materials for getting large bandwidth. Year 2015 has been proclaimed as the International Year of Light
and Light-based Technologies by The United Nations General Assembly in order to campaign for optics and photonics
research around the globe. Evolution of fiber optics and recent progress will be reviewed and presented. |
