Data Transfer Via Light Itself
Breakthrough in advanced material research increases our ability to bend light spectrum to our communicative needs.
It’s been almost 150 years since the first experiments in communicating via light were conducted by Alexander Graham Bell and his photophone. Now through atomic manipulation of advanced materials, scientists have squeezed even more bandwidth from fiber optic cables. Gizmag reports:
According to Penn State project leader Prof. John Badding, the arrangement of atoms in glass is haphazard, which impedes the passage of light through them. Crystalline substances like zinc selenide, however, have a highly-ordered atomic structure, which allows light to be transported over longer wavelengths.
