The analysis shows that wider and thicker arrayed waveguides, outsider fracture of arrayed waveguide, and larger channel space, could mitigate the deterioration of crosstalk. The SOI nanowire AWGs with different arrayed waveguide widths are fabricated by using deep ultraviolet lithography （DUV） and inductively coupled plasma etching （ICP） technology. The measurement results show that the crosstalk performance is improved by about 7 dB through adopting 800 nm arrayed waveguide width.展开更多

It is shown that the crosstalk must be less than -28 dB for a power penalty below 1 dB at a bit error rate of 1×10 -9 .It is found that when N =100,crosstalk power value is -20 dB with compensation power of 2-3 dB,so the compensation power is not ignored.展开更多
