	I didn't. That's why I mentioned 'transmission of energy'.

	Not really. It's the very same concept. Isotopically pure materials have lower losses when used as conductors (of heat, light, whatever).

	So anyway, I'd assume that people involved in optic fiber manufacturing were and are aware of the phenomenom so it's hard to imagine that they never tried to take advantage of it. And indeed you posted some news a few hours ago showing that they did? 

	I guess we'll have to wait and see if some company specifically tries 'your' idea...
