We have developed a new multilayered reflection film structure containing Ag films for achieving slab waveguide based optical transmission interconnections between large scale integrated chips for next generation high-speed computers. We applied Cr to both adhere the Ag to the SiO2 optical layer and to inhibit diffusion of Ag into SiO2. Although we found that Cr tends to decrease the reflectance, we found that it is possible to satisfy both adhesiveness and reflectance requirements by adjusting the film thickness
