          | Description: 
             This microscopic photonic 
            crystal uses a pattern of holes to sort a single lightwave into seven 
            wave- lengths, or colors. Light enters a solid strip that is bordered 
            by holes of various sizes that block certain wavelength ranges. After 
            filtering through the holes, the light exits the device as seven separate 
            wavelengths. |
