Silica-based 64-channel arrayed waveguide gratings (AWGs) with double functions and 0.4 nm (50 GHz) channel spacing have been designed and fabricated. On the same component, Gauss and flat-top output response spectra are obtained simultaneously. The test results show that when the insertion loss ranges from 3.5dB to 6.4dB,the crosstalk is better than -34 dB, the1 dB bandwidth is 0.12nm, the 3 dB bandwidth is 0.218nm, and the polarization-dependent loss (PDL) is less than 0.5 dB for Gauss response. When the insertion loss ranges from 5.8dB to 7.8dB, the crosstalk is better th an -30dB, the 1dB bandwidth is 0.24nm, the 3dB bandwidth is 0.33nm, and the PDL is less than 0.2dBfor flat-top response.
