Due to its excellent electrical, mechanical, thermal and optical properties, graphene has attracted much interest since it was discovered in 2004. Its two-dimensional nature and other remarkable properties meet the needs of surface plasmons and have greatly enriched the field of plasmonics. The paper will review recent advances and applications of graphene in plasmonic, including theoretical mechanisms, experimental observations, and meaningful applications. Due to its flexibility and good tunability, graphene can be a promising plasmonic material as an alternative to noble metals. Optical conversion, plasmonic metamaterials, light harvesting, etc. have already been realized in graphene-based devices, which are useful for applications in electronics, optics, energy storage, THz technology, etc. In addition, the excellent biocompatibility of graphene makes it a very good candidate for applications in biotechnology and medical science. Surface plasmons in graphene offer a compelling route to many useful photonic technologies. As a plasmonic material, graphene offers several intriguing properties, such as excellent electro-optic tunability, crystal stability, large optical nonlinearity, and extremely high electromagnetic field concentration. Thus, recent demonstrations of surface plasmon excitation in graphene using near-infrared light scattering] have attracted great interest. Here we present an all-optical plasmonic coupling scheme that takes advantage of the intrinsic nonlinear optical response of graphene. To generate plasmons, pulses of visible light in a free in-plane graphene sheet are used using difference frequency mixing of the waves to match both the wave vector and the energy of the surface wave. By carefully controlling the phase with matching conditions, we show that it is possible to excite surface plasmons with a defined wave vector and direction in a wide frequency range with high photon efficiency. Prospects for the practical use of graphene in plasmonics are discussed.
