Ultra-Compact Multimode Micro-Racetrack Resonator Based on Cubic Spline Curves

Micro-racetrack resonators have become one of the key components for realizing signal processing, generation, and integration in microwave photonics, owing to their high Q factor, compact footprint, and tunability. However, most of the reported micro-racetrack resonators are confined to the single-m...
