ICP Etched Waveguides




Arrayed Waveguides (Microscope)

Standard Optical Waveguides Resins
ZP-49 & ZP-51 series are thermally curable polymers based on highly fluorinated polyethers. Newly
formulated ZP-49 & 51 are improved the film quality, controllability of refractive index and solution
shelf life in comparison with former ZP1010M series. They are useful for optical waveguides and
optical thin film applications due to the low optical loss, high thermal and 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.

Availability and Storage
ZP-49 and ZP-51 solutions are available in 100 and 250 g quantities. These solutions 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.

Features

Low-optical loss
Thermal & Environmental stability
Controllable refractive index
Excellent mechanical properties


Applications

Optical power splitters
Variable optical attenuators
Optical Switches
Optical interconnections
Multi-mode waveguide devices

Reliability of Optical Waveguide Resins (ZP-49 and ZP-51)

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.
