摘要：
Femtosecond OTDR diagnostic techniques are used to investigate the optical properties of arsenic-doped silica-onsilicon waveguides. Results demonstrate that these waveguides have a relatively high refractive index (1.51) and a low loss (<0.5 dB/cm). Owing to the tight optical confinement of the guides, they will have important applications in areas in which high packing densities are required or where direct coupling from semiconductor lasers is needed. © 1990 Optical Society of America.
