Shining an appropriate light on such a wire from the outside would alter its refractive index (a measure of how fast light travelling inside the wire can move).
By the time we get to the party, for which the Colosseum is bathed in blue light as a backdrop for wire-dancing acrobats dressed in Valentino red, the Felliniesque-ness of it all can bring tears to our eyes.
The scandal came to light after the discovery of a wire-tap recording, made without judicial approval, of a conversation between South Korea's ambassador to the United States and a top executive from the Samsung Group.

It appeared as if carved out of stone, but in fact was made of vast segments of hot-wire-cut polystyrene with a light beech veneer.
The new technology, called an epidermal electronic system (EES), is based on a new class of micro-electronics that integrates miniature sensors, light-emitting diodes, tiny transmitters and refined wire-filament receivers.
In another bypass, they insert a wire into a silicon cover for an LED light that blinks red when the user enters an invalid code.

The surgeon placed a second wire and the patient reported seeing two spots of light.
Under normal conditions, this Lilliputian wire allows 1.5-micron-wavelength light to pass through.
The wire could therefore be switched on and off by the external light source.
That wire can ground a contact on the circuit board behind the light that triggers a function intended to allow the door to be opened with a remote button, bypassing all its security measures.

Threaded on a wire one-fifth the thickness of a human hair, these tiny seeds of light can be injected to activate special networks of light-sensitive neurons.

But, by drilling a series of evenly spaced holes into the wire, Dr Lim has created a periodic structure with a band gap that blocks such light.
In short, almost anywhere copper wire is used in close quarters or for fine quality--there is a promising opportunity for the light pipe.
