Paper Abstract

A polymeric 1 X 8 arrayed waveguide grating wavelength multiplexer with 1.6 nm (200 GHz) channel spacing has been designed and realized for operating around a 1550 nm wavelength. Two kinds of fluorinated polymers, perfluorocyclobutane and fluorinated poly(ether ketone) polymers were used for the low loss waveguides. As a core layer, fluorinated poly(ether ketone) polymer, which has a low propagation loss, a good processibility and high thermal stability up to 460 degree(s)C was newly synthesized. The propagation loss of a buried rib waveguide is less than 0.5 dB/cm at the 1550 nm wavelength. The refractive index difference between the core and the clad layers is 0.0273 ((Delta) equals 1.8%). The bending radius of curved waveguides is 7.5 mm. The device size is 39 mm long and 13 mm wide. Fiber-to-fiber insertion losses of the multiplexer are between 7 dB and 8 dB, and a 3-dB bandwidth is 0.6 nm. The crosstalk of all 8 channels is less than -24 dB. And the polarization (TE-TM mode) related wavelength shift is approximately 3.4 nm.
