Abstract

Thermally stable polymer waveguide was fabricated using polycarbonate as the core material. Polycarbonate is thermally stable up to 190 degrees C, has small birefringence of 0.003 and good otpical transparency at 1.3 micrometers . We used Cyclotene 3022 as the cladding material. The material has 0.45 percent lower refractive index than the core material, resulting in a good mode matching waveguide with a single mode silica fiber. Buried channel waveguides were fabricated by conventional photolithography and dry etching technique. The thickness of the guiding layer was 5.3 micrometers and the width of the waveguides varied form 3 to 8 micrometers . They showed an optical loss of less than 0.8 and 1.4 dB/cm at the wavelength of 1.3 micrometers for TE and TM polarizations, respectively.
