Summary :

We fabricated a tunable and polarization-insensitive arrayed-waveguide grating (AWG) 1616 multiplexer that operates around the wavelength of 1. 55 µm using fluorinated polyimides. The wavelength channel spacing was 0. 8 nm, and the 3-dB passband width was 0. 26 nm. The insertion loss at each channel was from 8 to 12 dB, and the crosstalk was less than -28 dB. 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.
