We demonstrated a hitless wavelength-channel-selective switch (hitless tunable add-drop filter) using thermooptic effect of double series coupled dielectric microring resonator. Using a dielectric material as the core, the response time was reduced to 1.05 (rise time) and 15 mu s (fall time), which are 15-fold and 100-fold faster than that of polymer material, and the reproducibility by the heat cycle test was also improved to less than 0.01 nm. The tuning range of wavelength-selective switch was expanded to 13.3 nm using the Vernier effect, and a large extinction ratio of more than 20 dB was realized.
