          | Description: 
             A few larger holes in Kyoto 
            University's optical waveguide allow specific wavelengths of light 
            to leak up through the surface of the chip. This provides an inexpensive 
            way to divide light into different wavelengths, an important capability 
            for tele- communications. |
