ABSTRACTWe synthesized novel cross-linkable fluorinated copoly(arylene ether sulfide)s for optical waveguide applications, which have high thermal stability, high optical transparency in the infrared communication region, and much smaller birefringence than other thermally stable fluorinated polyimides. The refractive index of the material can be easily controlled from 1.515 to 1.587 by changing the copolymer composition in the materials. The birefringence of the cured polymers were 0.0031∼0.0039 at the wavelength of 1.55 μm. This is much lower than those of fluorinated polyimides for optical waveguides. The refractive index of fluorinated poly(arylene ether sulfide) (FPAESI) after being stored at 100 °C for 1000 hr remains almost constant demonstrating the thermal stability. The propagation loss of the channel waveguides fabricated using reactive ion etching was less than 0.4 dB/cm at the wavelength of 1.55 μm.

AbstractThe mechanical, thermal, electrical and moisture absorption properties of rod-like, fluorinated polyimides and copolyimides developed in our laboratory are briefly reviewed. Further characterization work on the most promising candidates for interlayer dielectric applications is reported. This includes in- and out-of-plane refractive index measurements to estimate the isotropy of the dielectric constant, isothermal TGA measurements to assess thermal stability at processing temperatures and dynamic-mechanical analysis to ascertain the glass transition temperature and the mechanical modulus at temperatures in excess of the glass transition

Raman Response

ABSTRACTRapid thermal annealing has been used to initiate diffusion of Ti in LiNbO3 for the fabrication of optical waveguides. The sample with the most rapid initial ramp of temperature to 875 C was found to have the lowest propagation loss of 1 dB/cm. In order to more fully understand these channel waveguides, we have utilized Raman microprobe spectroscopy. Preliminary results suggest that the presence of the Ti in the LiNbO3 lattice dramatically alters the Raman response.

UV-Writing Poly(FPS-co-GMA) for optical waveguide was synthesized and the refractive index of the polymer film was tuned in the range of 1.460~1.555 at 1550 nm by mixing with bis-phenol-A epoxy resin. The film, which was made by spinning coated the Poly(FPS-co-GMA) with photo initiator, had good UV light lithograph sensitivity. The optical waveguides with very smooth top surface were fabricated from the resulting polymer by direct UV exposure and chemical development. The propagation losses of the channel waveguides were measured to be below 0.6 dB/cm at 1550 nm.
