氟化聚合物光谱响应平坦化阵列波导光栅的优化设计和制备
Optimum Design and Fabrication of a Fluoropolymer Arrayed Waveguide Grating with Flat Spectral Response
摘要
Abstract
In terms of the transmission theory of the arrayed waveguide grating,by using Fluoropolymer(PFS-co-GMA) ,the paraneter optimization is performed for a 17 x 17 AWG multiplexer. In the fabrication of the polymeric arrayed waveguide grating (AWG) device,the cores of the channels and the arrayed waveguides exhibit trapezoid cross-sections instead of originally designed rectangular ones after the reactive ion etching and the stean-redissolution,causes the phaeshift of the light propagating in the AWG,results in the shift of the transmission spectrum, and bring about the variation of the crosstalk. In this paper,by employing the equivalent energy flow method,the AWG parameters have been fixed,and a polymer AWG multiplexer with flat have been designed and fabricated. Measured results show that the central wavelength is 1550.865nm,3-dB bandwidth is about 0.478 rnn, insertion loss is 10.5 dB,crosstalk is about - 21.5dB.关键词
