Nanotechnology Now Shanhui Fan (Image credit: Rod Searcey) Abstract: Among the first lessons any grade school science student learns is that white light is not white at all, but rather a composite of many photons, those little droplets of energy that make up light, from every color of the rainbow - red, orange, yellow, green, blue, indigo, violet. With new optical device, engineers can fine tune the color of light Stanford, CA | Posted on April 23rd, 2021 Now, researchers at Stanford University have developed an optical device that allows engineers to change and fine-tune the frequencies of e...

 E-Mail Among the first lessons any grade school science student learns is that white light is not white at all, but rather a composite of many photons, those little droplets of energy that make up light, from every color of the rainbow - red, orange, yellow, green, blue, indigo, violet. Now, researchers at Stanford University have developed an optical device that allows engineers to change and fine-tune the frequencies of each individual photon in a stream of light to virtually any mixture of colors they want. The result, published April 23 in Nature Communication, is a new photonic archit...
