| Abstract | March 28-31, 2017 Barcelona (Spain) Photonics of two-dimensional materials: graphene and beyond Qiaoliang Bao1,* Presenting Author Co-Authors: Shaojuan Li2, Yupeng Zhang1 1 Department of Materials Engineering, Monash University, Clayton, Victoria 3800, Australia 2FUNSOM, Soochow University, Suzhou 215123, P. R. China Contact@E-mail: qiaoliang.bao@monash.edu Here we would like to review our recent progresses on the photonic applications of graphene and other two-dimensional (2D) layered materials.[1,2] Firstly, we report the development of new saturable absorbers based on graphene heterostructures and other 2D materials, including graphene/Bi2Te3[3], black phosphorus[4] and self-doped plasmonic 2D Cu3-xP nanosheets[5]. Depending on their nonlinear optical properties, both high energy Q-switched laser and ultrafast mode-locked pulse generation were demonstrated. Secondly, we fabricated a highly efficient hybrid photodetector that consists of graphene covered with dispersive organolead halide perovskite (CH3NH3PbBr2I) islands.[6] We also demonstrated a broadband photodetector based on graphene-Bi2Te3 heterostructure.[7] Furthermore, we developed new methods to grow and transfer large area single crystal WS2 [8], large area MoS2/WS2 heterojunction [9], and monolayer-bilayer WSe2 heterojunction [10], and demonstrated their applications for photodetectors. Thirdly, we investigated plasmonic excitation and THz modulation in graphene/Bi2Te3[11], graphene nanoribbon [12] and 3D graphene [13] using either spectroscopic or real space imaging techniques. The important discoveries include the plasmonic coupling of two Dirac materials [11], excitation of high-order mode [13] and edge chirality-related plasmonic broadening [12]. Last, we report our recent progress on the synthesis of 2D organic-inorganic hybrid perovskite nanosheets as well as their optoelectronic applications.[14-17] In summary, the advances of photonics of 2D materials may pave the way for the integration of next generation hybrid silicon photonic circuit. |
