| Researchers at JQI have designed and tested new chips that reliably convert one color of light (represented by the orange pulse in the lower left corner of the image above) into many colors (represented by the red, green, blue and dark grey pulses leaving the chip in the lower right corner). The array of rings—each one a resonator that allows light to circulate hundreds of thousands or millions of times—ensures that the interaction between the incoming light and the chip can double, triple and quadruple its frequency.
