visible light frequency generator

I was just wondering if there are standard frequency generators
that can create frequencies all the way up to visible light. (i.e.
frequency = 10^14 or 10^15)

Thanks.

Light bulbs work, but they're noisy. Lasers are better.

An LED does that, with various wavelengths of light
available. Depending on which color*.
(*From the department of redundancy department.)

You were looking for something with
a bunch of components, none of which,
by itself, creates light when a voltage
is applied?

Sounds like the definition of a Carbon Arc!
