Title: Enhanced Light Matter Interaction Over A Surface “Rainbow”

Abstract: 

The concept of Trapped “Rainbow” Storage of Light was first proposed in 2007 [1]. Over the past approximately 15 years, it has seen numerous intriguing optical research achievements [2]. First, I will share the research advancements in the field of "rainbow trapping" over the past 15 years and introduce some of the attempts made by my research group from both fundamental physics [3,4] and practical application perspectives [5]. Specifically, I will introduce the general principle of rainbow trapping effect based on Metamaterials and plasmonics platforms, and its applications in enhanced light-matter interaction, notably including on-chip biomedical diagnostics [6] and miniaturized spectroscopy for deep learning [7].
