Design,Fabrication,and Testing of SingleSide Alignment of 16×0.8nm Arrayed Waveguide Grating

Abstract: A novel design of 100GHzspaced 16channel arrayed-waveguide grating (AWG) based on silica-on-silicon chip is reported.AWG is achieved by adding a Ybranch to the AWG and arranging the input/output channel in a neat row,so the whole configuration can be aligned and packaged using only one fiberarray.This configuration can decrease the device’s size,enlarge the minimum radius of curvature,save time on polishing and alignment,and reduce the chip’s fabrication cost.
