X-rays for telecommunications?
|
|
|
Hi:
Has the use of x-rays for telecommuncations ever been considered? I
imagine that x-ray photons would have more bandwidth than
visible-spectrum photons. Other than bandwidth, are there any
advantages to using x-rays instead of light. One major disadvantage, is
the fact that x-rays could injure humans and possible some metal
equipments by knocking electrons off the atoms -- one solution to this
would be to use lower rate x-rays photons per second so that the amount
of x-ray power does not reach the danger level.
Thanks,
Radium |

Things that produce x-rays are highly regulated for obvious health
and safety reasons.
Since there is no such thing as a good x-ray mirror, there is no way
to make a gain antenna at x-ray frequencies so power levels would
have to be high.
Visible light has potentially far more bandwidth than is currently
used since even at light frequencies there are limitations to the
modulation and demodulation technologies.
Do you stay up at night to come up with these ridiculous ideas?

So I guess 400 nm is the sweet spot between most bandwidth and
non-ionizing radiation. Am I right?

No, you are wrong as usual.
The "sweet spot" is where the light emitters and detectors can be
most economically produced.
The bandwidth limitations at light frequencies are in the modulation
and demodulation technologies, not in the theoretical limitation
of the light wavelength.
There is no technology in existance that can utilize more than a
small fraction of even infrared's theoretical bandwidth.
