New-generation ultra-low loss silicon photonic waveguide and devices

We propose the concept of silicon photonics beyond the singlemode regime with ultra- low-loss propagation of 0.065 dB/cm. The state-of-art micro-racetrack resonator, high-resolution microwave filter and 100-cm-long delayline are demonstrated with standard 220-nm-SOI (silicon- on-insulator) MPW-foundry processes.
