#Reseachers Create First Integrated Circularly Polarized Light detector on a Silicon chip What do you get when you combine some biomimicry, metamaterials and nanowires?
It turns out to be integrated the first circularly polarized light detector on a silicon chip. Its development could usher in a new generation of portable sensors that can use polarized light for applications ranging from drug screening to quantum computing.
Researchers at Vanderbilt University have used silver nanowires to fabricate a metamaterial that is capable of detecting polarized light in a way not unlike the way cuttlefish, bees,

In contrast to non-polarized light, in which the electric fields of the photons are oriented in random directions,
With circularly polarized light, the plane is continually rotating through 360 degrees.)One of the distinguishing capabilities of circularly polarized light (CPL) is that it can discern the difference between right-handed and left-handed versions of molecules property known as chirality.

A lot of colors you see in nature are due to wavelength selective light absorption in organic molecules which cannot withstand high temperatures,
Ultraviolet light destroys organic dye molecules over time, leading to color change and fading. The new technology may hold promise for many applications such as for jewelry, automotive interior trim, aviation, signage, colored keypads, wearable and electronic displays.
