Optical transistors and nano-features for security applications
We study a novel type of optical transistors using metallic nanohole arrays. The transistors operate based on strong coupling between surface plasmon polaritons and excitons via the metallic nanofeatures. One such transistor can act as a control unit, a photo-detector or a modulator and can open innovative practical applications in many fields. The physical structures of the transistors are flexible, light weight and ultrathin, so that they can be integrated in large scale with other types of thin-film optoelectronic components. In this project, we will build these transistors into our industry partner’s patented technologies for authenticating secure documents using built-in optoelectronic circuits and nano-structures. The proposed research can potentially enable reliable security applications that can help prevent loss from counterfeiting
