Fig. 4. (a) Optical loss of the proposed waveguide. It shows a low-loss performance in the bandwidth with a broadband athermal property. (b) Effective-TOC curves of the micro-ring resonators with different ring radii. (c) Bending loss with different radii. This shows a low-loss performance and a stable athermal property of the proposed broadband athermal micro-ring resonators.
