摘要
The fabrication of silica-on-silicon channel guides by spin-coating and rapid thermal annealing (SC-RTA) of sol-gel glass doped with gallium, germanium and phosphorus oxides is described, and methods of depositing clear, crack-free films are discussed. Low loss is only obtained for lightly-doped guides with controlled process temperatures.
