摘要：

GeO2-doped silica waveguides with a high refractive index difference of 1.5% are successfully fabricated on Si substrates. Their propagation loss, measured in 200-cm-long test circuits with a minimum curvature radius of 2 mm, is 0.073 dB/cm. The waveguides are used as high-density integrated planar lightwave circuits in 1 x 4 Mach-Zehnder (MZ) type multi/demultiplexers for optical frequency division multiplexing (FDM) transmission systems and in modified MZ type multi/demultiplexers with a ring resonator, which have a compact device size of 15 x 50 mm2 and a frequency spacing of 10 GHz.
