Population inversion in monolayer and bilayer graphene.
The recent demonstration of saturable absorption and negative optical conductivity in the Terahertz range in graphene has opened up new opportunities for optoelectronic applications based on this and other low dimensional materials. Recently, population inversion across the Dirac point has been observed directly by time- and angle-resolved photoemission spectroscopy (tr-ARPES), revealing a rela...
متن کاملTransmission Properties of the Periodic Structures Based on Graphene Nonlinear Optical Conductivity in a Terahertz Field
By developing the terahertz (THz) technology, in addition to generators and detectors of THz waves, the existence of some tools such as modulators and filters are needed. THz filters are important tools for various applications in the field of chemical and biological sensors. Linear and nonlinear optical properties of the graphene have attracted lots of attention. In fact graphene exhibits vari...
متن کاملGraphene terahertz injection lasers: Concepts and feasibility of realization
The gapless energy spectrum of electrons and holes in single graphene layers (SGLs), graphene bilayers (GBLs), and non-Bernal stacked multiple graphene layers (MGLs) opens up prospects of creating graphene-based terahertz (THz) and infrared (IR) lasers. The interband population inversion in such lasers can be achieved, for instance, by optical pumping [1]. However, the excess energy received by...
متن کاملTerahertz surface plasmons in optically pumped graphene structures.
We analyze the surface plasmons (SPs) propagating along optically pumped single-graphene layer (SGL) and multiple-graphene layer (MGL) structures. It is shown that at sufficiently strong optical pumping when the real part of the dynamic conductivity of SGL and MGL structures becomes negative in the terahertz (THz) range of frequencies due to the interband population inversion, the damping of th...
متن کاملElectronic Transmission Wave Function of Disordered Graphene by Direct Method and Green's Function Method
We describe how to obtain electronic transport properties of disordered graphene, including the tight binding model and nearest neighbor hopping. We present a new method for computing, electronic transport wave function and Greens function of the disordered Graphene. In this method, based on the small rectangular approximation, break up the potential barriers in to small parts. Then using the f...
