Layer-Tunable Third-Harmonic Generation in Multilayer Black Phosphorus
Black phosphorus has been the subject of growing interest due to its unique band structure that is both layer dependent and anisotropic. While many have studied the linear optical response of black phosphorus, the nonlinear response has remained relatively unexplored. Here we report on the observation of third-harmonic generation in black phosphorus using an ultrafast near-IR laser and measure ...

متن کاملElectrically tunable coherent optical absorption in graphene with ion gel.
We demonstrate electrical control over coherent optical absorption in a graphene-based Salisbury screen consisting of a single layer of graphene placed in close proximity to a gold back reflector. The screen was designed to enhance light absorption at a target wavelength of 3.2 μm by using a 600 nm-thick, nonabsorbing silica spacer layer. An ionic gel layer placed on top of the screen was used ...
متن کاملObservation of an electrically tunable band gap in trilayer graphene
A striking feature of bilayer graphene is the induction of a significant band gap in the electronic states by the application of a perpendicular electric field1–7. Thicker graphene layers are also highly attractive materials. The ability to produce a band gap in these systems is of great fundamental and practical interest. Both experimental8 and theoretical9–16 investigations of graphene trilay...
متن کاملElectrically tunable graphene plasmonic quasicrystal metasurfaces for transformation optics
The past few years have witnessed tremendous achievements of transformation optics applied to metallic plasmonic systems. Due to the poor tunability of metals, however, the ultimate control over surface plasmons remains a challenge. Here we propose a new type of graphene plasmonic (GP) metasurfaces by shaping the dielectrics underneath monolayer graphene into specific photonic crystals. The rad...
