How can a beam of light tell the difference between left and right? Tiny particles have now been coupled to a glass fiber. The particles emit light into the fiber in such a way that it does not travel in both directions, as one would expect. Instead, the light can be directed either to the left or to the right. This has become possible by employing a remarkable physical effect – the spin-orbit coupling of light. This new kind of optical switch has the potential to revolutionize nanophotonics. (1)
Left.
Right.
Up.
Down.
Name things.
And you will start discovering “impossibilities”.
Stop naming things.
And just everything is possible.
We have limited our selves.
To get free all we have to do is turn right. And left. And up. And down.
Be everywhere. And nowhere at the same time. And just let the light go wherever it wishes to go…
