Research Interests

Prof. Dai's research is focusing on manipulating the polaritons in nanomaterials to solve the key scientific problems of photoelectric signal conversion at the micro-nano scale, which is essential to develop the next generation of high-speed photon chips. The creative research results they have been achieved include: for the first time, the wideband tuning graphene plasmon with 100-fold wavelength compression has been achieved, which provides the important basis for optical signal input; besides, they first discovered a new kind of hybrid mode form coupling between plasmons and phonons in the heterostructure, which can increase the lifetime of plasmons by ten times, matching the design requirements of the waveguide; in addition, the electron tunneling effect derived by optical fields was observed for the first time in the single-walled carbon tubes, which offers a high-temporal and coherent femtosecond ultrafast electron source to realize high-speed electro-optical signal conversion.
