摘要：

Racetrack microring resonators with improved quality factors based on asymmetric Bezier waveguide bend for silicon nitride photonics integration platform have been proposed and demonstrated experimentally in this paper. The asymmetric Bezier waveguide bend can reduce bend loss which is one of the major limitations of the Q factor of racetrack microring resonators. The proposed racetrack microring resonator structure based on an asymmetric Bezier bend waveguide can significantly improve the Q factor while maintaining the same device area. Such racetrack microring resonators with superior performance can help improve the performance of on-chip devices and further promote the development of a photonic integration platform.
