An ultrahigh-Q compact silicon racetrack resonator based on multimode waveguide bends (MWBs) is proposed and demonstrated. The MWB is defined by a combination of cubic and circular curves. The free spectral range (FSR...

The bipolar spherical cavity SLED has been widely used in accelerator and high power microwave fields as it has high quality factor and is much tighter in volume than the traditional structure. However, due to its hig...
