摘要：

A novel method of flattening the passband of an arrayed waveguide grating with a small excess loss, which employs a new concept that uses the assist of the weak first-order mode, is described. A 16-channel 100 GHz-spacing demultiplexer with a fibre-to-fibre loss of less than 3.6 dB and a flattened excess loss of 1.85 dB is demonstrated. The I dB down passband is widened 2.2 times.
