| This photograph shows a copper-coated hollow silicon waveguide chip. The hollow waveguide channels guide 1.55 micron radiation between the circuit of discrete components. Each component is held in an DRIE etched alignment slot. A lid, which is not shown, forms the upper wall of all the waveguides. (Credit: QinetiQ) |
