The buzz is that....
Graphene has Optical Gain Properties; the researchers took epitaxically developed grapheme sheet and bombarded it with 1.55 eV laser pump of very short duration pulses approximately 35 fs.
The amount of light reflected back from the sheet during experiment was amount of light sent. The team of researchers feels that this is because of unique property of grapheme or Optical Gain Properties.
A matter is said to have optical gain properties when shined by a light sources reflects back more light that it received. The property is useful in making of opto electric devices like amplifiers, absorbers, lasers and modulators.
Graphene was discovered in 2004 and since then it’s known to surprise engineers and scientists. In coming years team of researches feels that telecommunication should be grapheme powered.
