Optical resonators with high-quality factors (Q-factor) constitute the main building block for many photonic devices capitalizing on light-matter interactions, ranging from light emitters to biochemical sensors. While a high Q-factor enhances light-matter interactions, it also limits the device operation bandwidth. Here we propose and numerically analyze a… CONTINUE READING
