10. The transmission of s- and p-polarized light is dependent on the tilt angle of the filter. At a tilt angle of ∼15°, s-polarized light is blueshifted ∼0.3 nm more than p-polarized light and the ratio of transmitted s- to p-polarized light is 1:1.3. Both of these differences increase with tilt angle.

17. We expect the actual feature size to vary from the target feature size due to standard broadening effects in the construction of the SU-8 masters.
18. The measurement was made on a uniform region of the channel. In order to measure % reflectivity, we divide the p-polarized data by the corresponding s-polarized data and a correction factor for polarization dependent transmission effects at the operating tilt angle. The correction factor is the ratio of the intensity of p-polarized light to s-polairzed light in the absence of surface plasmons.
