摘要：

A polarisation-insensitive arrayed-waveguide grating multiplexer is successfully fabricated on an Si substrate by adjusting the thermal expansion of dopant-rich silica-based glass to that of Si. The change in wavelength due to polarisation was kept to within 0.03nm in a 1 x 8 arrayed-waveguide grating multiplexer with a flat and wide passband having a 3dB bandwidth of 0.9nm and a wavelength spacing of 1.6nm.
