Merged bound states in the continuum for giant superchiral field and chiral mode splitting

|
By Kang Du, Yimu Chen, Shumin Xiao, Hamdi Barkaoui
| Physical Review B
Abstract Enhanced circular dichroism (CD) signal is crucial for ultrasensitive detection of chiral species. This purpose strongly relies on the construction of superchiral field in achiral resonant nanostructures. Despite the progress, the research on superchiral fields and their related physics is fundamentally restricted. Here, we demonstrate an approach to construct superchiral field in achiral metasurfaces and explore its impact on chiral mode interaction.
