Abstract
Recently, chiral photonics using circularly polarized (CP) light have led to the growing interest in applications such as quantum communication and optical encryption. The central challenge for achieving such chiral optoelectronics is to develop the electronic devices that are capable of detecting distinguishingly the handedness of incident CP light. Furthermore, the CP light detectors responding to the wavelengths in the near-infrared (NIR) region are required in order to fully extend their practical applications. In this regard, we have demonstrated high-performance NIR CP light-sensing organic phototransistors based on a conjugated polymer by integrating a selective NIR-reflecting cholesteric liquid crystal network film. In this presentation, we will show our facile strategy for developing the NIR CP light-sensing chiral optoelectronic devices as well as demonstrate their actual application to a cryptographic authentication key utilizing the physically unclonable function arrays.
