摘要
A resonator-system (100) of a planar waveguide system includes two or more resonators (112-1,112-2) that are controlled using thermo-optic heaters (122-1,122-2). The resonator-system is coupled to an input waveguide (10) and an output waveguide (12). The heaters control the coupling and resonance frequencies of the resonators. By shifting pairs of resonance frequencies in opposite directions, ON/OFF switching functions are provided. By shifting pairs of resonance frequencies by different amounts and in different directions, variable splitting functions, such as variable optical attenuation and tapping, are provided.
