Unlike erbium-doped fiber amplifiers (EDFAs), which boost wavelengths in the 1530-1610 nm range, a Raman amplifier can increase the signal strength of any wavelength by pumping at 13THz more than ...

National Science Day is observed every year on February 28th to mark the discovery of the Raman Effect by Sir C.V. Raman in 1928. The day is a remembrance of his pioneering work and a celebration ...
