Transfer function method is used in the simulation and error analysis of AWG with width fluctuations. The 25-channel 200 GHz AWG exhibits central channel insertion loss of 6.7 dB, crosstalk of-13 dB, and central wavelength of 1 560.55 nm. The error analysis can explain the experimental results of 25-channel 200 GHz AWG well. By using deep ul- traviolet lithography (DUV) and inductively coupled plasma etching (ICP) technologies, the devices are fabricated on sili- con-on-insulator (SOI) substrate.展开更多
