We present a wavelength selective switch (WSS) that is based on two Vernier 2nd-order microring resonators (MRRs). Each 2nd-order MRR has two racetrack cavities with perimeters of 78.8 $\mu$m and 105.2 $\mu$m, respectively, producing a free spectral range around 22 nm. The WSS exhibits a 3dB bandwidth of 85 GHz and an extinction ratio around 10 dB.
