Direct Mapping of Intrinsic Topology of Bound States in the Continuum via Nonlinear Emission
Shuzheng Chen, Hongwei Wang, Zijian He +7
The direct mapping of the intrinsic topology in a leaky photonic band is crucial and challenging in topological photonics. For instance, observables in bound states in the continuu…
