Abstract
Identifying molecular handedness using circular dichroism is limited to large volumes and high concentrations.
Circularly polarized luminescence (CPL) potentially offers higher sensitivity at low molecular concentrations than
absorption-based circular dichroism. However, it suffers from low fluorescence intensity, preventing the detection of
low circular polarization contrasts, which makes detecting decreasing chiral molecule concentrations extremely
challenging. Nanophotonic structures open a route to circumvent these problems. High-refractive-index resonators like
silicon nanodisks can both increase circular dichroism and enhance molecular fluorescence. Related Projects
