Effect of film compatibility on electro-optic properties of dye doped polymer DR1/SU-8

- UV exposure and high temperature dealing can enhance the cross-linking and solidity of DR1/SU-8.
- Resistivity of polymer claddings can indicate the origin of EO response distinction of core-cladding couples.
- NOA73 as cladding suggests low optical loss, strong and stable EO response for DR1/SU-8 waveguide.
- The series of characterizations in the paper can be applied to find out favorable passive cladding for EO polymer waveguide.
