Abstract
Negative photoresist films (HNR-80 and HNR-120) are fabricated and characterized for waveguiding purpose. Various waveguiding parameters, namely, refractive index, thickness, propagation losses, and birefringence of the photoresist films are evaluated. Propagation losses are optimized to the value of 0.29 dB/cm for both materials. These photoresist materials show excellent transmission with almost no absorption in the wavelength range of 400 to 900 nm. The waveguides are polarization insensitive for various temperatures. Considering these properties, these materials offer a good option to use as waveguiding materials in integrated optics.
