| Abstract: | The insertion loss of arrayed waveguide grating (AWG) is studied. Methods for analyzing the losses and optimization schemes for low-loss devices are discussed. The structure parameters are optimized and an ultra low loss 8-channel 200 GHz-spacing AWG is designed. The insertion loss of central channel is 1.37 dB, lower than one-half of current commercial device. The work is with guidance function to the design of AWG. |
