An analysis of sidewall grating filters with sinusoidal perturbation is presented. Measurements indicate that the maximum extinction-ratio of the filters is limited by the polarisation scattering in the waveguide. We show that TM polarisation absorbers and filters offer a simple design solution that can provide extinction ratio values up to 60 dB.
