Abstract
By choosing Polymethyl Methacrylate-glycidyl Methacrylate[P(MMA-GMA)] with a low absorption loss at 650 nm as the cladding material of a waveguide,and taking the bisphenol A epoxy resin as the refractive index modifier,the cross section size of a single mode waveguide was designed according to the refractive index of the cladding and core material.Then the layout of a 16-channel Arrayed Waveguide Grating(AWG) was designed and optimized using beam propagation method.The Optiwave software was used to simulate the optical propagation characteristics of the AWG,and results show that the channel spacing is 0.845 01 nm,the device insertion loss is less than 14 dB,and the crosstalk is less than-25 dB.
