A triplexer is fabricated based on SOI arrayed waveguide gratings (AWGs).Three wavelengths of the triplexer operate at different diffraction orders of an arrayed waveguide grating. The signals of 149Onto and 1550nm,which are input from central input waveguide of an AWG,are demultiplexed and the signal of 1310nm,which is input from central output waveguide of an AWG,is uploaded.The tested results show that the downloaded and uploaded signals have flat-top response.The insertion loss is 9 dB on chip,the nonadjacent crosstalk is less than -30 dB for 1490nto and 1301 nm,and is less than -25 dB for 1550nm,the 3dB bandwidth equates that of the input light source.
