摘要：

The phase errors caused by deviations in the designed lengths of the optical paths in silica-based arrayed-waveguide grating (AWG) multiplexers were measured using Fourier transform spectroscopy. The measurement accuracy was +/- 1 degrees. The phase errors in an AWG multiplexer with a channel spacing of 10GHz and a channel crosstalk of -15dB were randomly distributed between -122 and 90 degrees.
