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.
