Abstract: A new arrayed waveguide grating(AWG) multiplexer was fabricated by using synthesized 3F-PES as the waveguide core. The DSC and TGA exhibit T g and the temperature at which 5% mass loss occurred in air of 3F-PES are 170 and 542℃, respectively. The infrared absorption spectrum indicates that 3F-PES has a high optical transparency in the infrared communication region. The AFM exhibits the roughness of the 3F-PES film is 0.35 nm. The arrayed waveguide grating(AWG) multiplexer was fabricated by using the 3F-PES as the waveguide core. The AWG multiplexer exhibits a wavelength channel spacing of 1.603 nm and a center wavelength of 1 550.15 nm.
