Re: Resolution Beyond the Classical Limit

However, you can also use a prism and shine a beam into it. Under total
reflection, there is an evanescent wave at the air-glass reflecting
interface. If this interface is placed near the core of a fiber (within a
wavelength but not touching and assuming the fiber can support a mode for
the light) the wave will coupled into the fiber and propagate.

So, does all the light couple? If so, I presume the total reflection
disappears.

Also, is this more advantageous than direct coupling with a lens?
I presume it must be easier to align or something?

Is there a name for this technique so I can go Google it?
