Swiss scientists have created the first semiconductor laser consisting solely of elements of main group IV (the carbon group) on the periodic table. Simply, this means that the new device is directly compatible with other elements in that group – such as silicon, carbon, and lead – and so can be directly incorporated in a silicon chip as it is manufactured. This presents new possibilities for transmitting data around computer chips using light, which could result in potential transfer speeds logarithmically faster than possible with copper wire and using only a fraction of the energy of today’s integrated circuits...
