摘要：

A 256 channel arrayed waveguide grating with a 25 GHz spacing was fabricated on a 4 inch Si wafer using 1.5% Delta silica-based waveguides with a minimum bending radius of 2mm. By improving the fabrication methods of 1.5% Delta waveguides, we have obtained an on-chip loss of 2.7 - 4.7dB, a far-end crosstalk of < -40dB and a polarisation-dependent wavelength shift of < 0.025nm.
