Standard Optical Waveguides Resins
ZPU12 and 13-RI series are photoactive UV curable fluorinated resins based
on acrylate. They
are useful for optical waveguide devices and optical thin film applications.
These coating resins
have low optical loss for optical communication wavelengths, small
birefringence, and excellent
environmental stability. To be used for various waveguide structures,
precise and continuous
control of refractive index is available by blending of polymer solutions
with standard refractive
index. To achieve the best film quality, a nitrogen environment is
recommended during the UV
exposure.
Availability and Storage
ZPU12 and 13-RI resins are available in 100 and 250 g quantities. The
ZPU12-RI series should be
stored in a dark and cool place under 25°C
in the bottle with a tight cap.
Moisture should be
avoided because it may affect the product performance.

Reliability of Optical Waveguide Resins (ZPU12-RI and ZP13-RI)
During the test, all of the films were not peeled off from the
Si wafer substrate and their refractive
index were not changed.
The test films were made by spin coating and curing
on the Si wafer after treatment of the
adhesion promoter.
