    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)

    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!
