why no UV communication system?

[bhargava]

Hi,
I was just wondering why dont we have a Ultra  Violet communication technology?

Well we know that higher the freq. easier the commminication the UVs are higher freqs, easier to produce also it helps us increase the availble spectra as all of us know frequency is a valuble resource so why there is no UV comm. system in vogue.
Or atleast is there  any research going on in the area
clarify please.....

UV emitting LEDs are luckily low powered, so don't go very far. It is lucky that they are low powered because UV causes eye and skin damage. Its wavelength is approaching x-rays.

Even if we do use it,what amount of bandwidth can it provide?
i guess very large but as they are harmful they are not put to commercial use.
the same is the reason for not so much progress for microwave links over Optical communication.i.e microwaves are harmful ;D
