Photonic crystal waveguide. Computer representa- tion of light being bent through a right angle in a photonic crystal. The colours show the light wave in the crystal. The white circles show the structure of the photonic crystal. The structure prohibits the propagation of a specific frequency of light. If a defect is made in the crystal,such as the path seen here,light of such a frequency has no option but to follow it. Photonic crystal waveguides can bend light in a far shorter distance than conventional optical fibres. This makes it possible to create much smaller optical components,which could lead to the creation of optical computers. Work done at MIT,USA | |
