• We fabricated a tunable and polarization-insensitive arrayed-waveguide grating(AWG)16×16 multiplexer that operates around the wavelength of 1.55μm using fluorinated polyimides. The wavelength channel spacing was 0.8nm, and the 3-dB passband width was 0.26nm. The insertion loss at each channel was from 8 to 12dB, and the crosstalk was less than -28dB. The transmission pass wavelength was tuned over a wide range of 6 nm by heating from 24℃ to 64℃. The slope of the temperature dependence of the pass wavelength was -0.15 nm/℃, which is ten times that of a silica-based multiplexer. Polarization-insensitivity was achieved by fabricating a film AWG multiplexer, which was formed by removing the silicon substrate and annealing at 350℃. The polarization-dependent wavelength shift was smaller than the spectrum analyzers wavelength resolution of 0.1 nm.
