摘要: A novel polarization-beam splitter/switch with a Mach-Zehnder interferometer configuration was fabricated using silica-based planar lightwave circuit (PLC) on silicon substrate. The realized by accurately controlling the waveguide birefringence and phase state laser trimming two kinds of stress-applying amorphous film widths 50 /spl mu/m 95 mu/m. Fiber-waveguide-fiber insertion loss 0.5 dB crosstalk attenuations over 25.6 were attained. >
