This study is using Focused Ion Beam technology and soft micro modeling technology to manufacture three side gratings of polymer ridge waveguide to produce polymer Bragg grating filter. This process first use focused ion beam etching process to produce polymer grating components then the polymer grating waveguide is used by micro-mold transfer technologies . At last we use a scanning electron microscopy (SEM) and optical microscope (OM) to observe and record test results.
