The ancient greek lit signal fires on hilltops to relay news of the fall of troy. Though fundamental research was carried through, it did not draw the attention until 1960 when T. Maiman invented the Laser. In 1880, Bell invented photophone whereby he can be attributed for the use of 1st practical scheme for optical communication. I would say, the journey of optical communication begets from 1970. By K. Ashique Ahmed Rafi
