High Quality Factor PECVD Si3N4 Ring Resonators Compatible with CMOS Process

Not Accessible

Your library or personal account may give you access

Abstract

We demonstrate high-confinement Si3N4 resonators with intrinsic quality factor more than 1 million using standard PECVD process. We show that by addressing scattering, the loss at 1.6 μm can be as low as 0.4 dB/cm.
