Because it is an ultraviolet curable resin, it is possible to fabricate waveguides by various methods.
- direct exposure method
- RIE method
- Stamper method
Feature
- Refractive index can be specified in increments of 0.001
- excellent light transmission
- Viscosity can be adjusted, and film thickness controllability during spin coating is good.
- Refractive index can be controlled in the range of 1.43 to 1.62 with an accuracy of ±0.005
[Example of application] Cladding of optical waveguide
It has excellent flatness and refractive index matching, and is also available in a solder heat resistant grade, so it can also be applied to interlayer insulating films.
(Epoxy resin is used for clad/MM waveguide core)
