Integrated optical ring resonators are essential elemental components for integrated optical circuits. An ultrasmall thermo-optical microring resonator with two bus waveguide-configuration based on surface plasmon polariton waveguide is theoretically analyzed. The thermo-optical coefficient, the temperature-dependent amplitude attenuation coefficient and(More)
A novel electromagnetic wave mode transducer for TE20 mode in a substrate integrated waveguide is proposed. The transducer contains two basic parts: the over-moded waveguide cavity section and the fundamental mode rejection section. To obtain a wideband mode transducer, an over-moded waveguide cavity is designed with multiple frequencies resonance. In the(More)
