High-Sensitive Refractive Index Sensing Enabled by Topological Charge Evolution

High-Sensitive Refractive Index Sensing Enabled by Topological Charge Evolution

A high-sensitive refractive index sensor is proposed and demonstrated by utilizing merging bound states in the continuum, namely a set of integer topological charges in the momentum space. Through varying cladding refractive index nc, the topological charges continuously depart from the merging stat...
