제목 Nanophotonic Design of Chiral Organic Photodetectors
초록 Chiral optoelectronics devices, such as chiral light-emitting diodes emitting circularly polarized light (CPL) with a specific handedness and chiral photodetectors that can detect the handedness of incident CPL, are attracting interest because of their potential applications including chiral molecular sensing, spintronics, displays to quantum information processing. Organic optoelectronic devices are a promising platform to achieve both high efficiencies and dissymetry factors (g), because molecules possessing structural chirality can be directly incorporated in these devices. However, the characteristics of chiral molecules developed so far suggest that there exists a fundamental trade-off between g and the absorption (or emission) efficiency. I will introduce a nanophotonic approach to overcome this trade-off, discussing the design principle of chiral plasmonic nanocavity that serves as a platform for chiral organic photodetectors.
