We present simulations and experimental measurements of transmission properties of photonic crystal slab structures defined by air holes etched into polymeric slab waveguides. Geometric defects in otherwise regular photonic crystal slab structures strongly localize optical fields, forming resonators of significant quality factors that may e.g. be used in novel filtering devices for optical telecommunications (1330 and 1550 nm). We show what influence parameters like etching depth and vertical contrast have on attainable quality factors and on transmission as well as coupling efficiencies. First results are presented on the use of ultra low index substrates.
