A dye molecule shows how light can transfer information
THE world of today cannot do without transistors. Used to switch and amplify signals in the integrated circuits, they are essential for any electronic device to work efficiently. As of now silicon is the principal component of a transistor. Its electrons, which have conducting properties, allow for fast transmission of information. It could still be faster but for the loss of energy, say researchers. This is where light can step in as a conductor, with a speed of 299,792,458 metres per second.
