Recently, originating from the emerging and intensive research of graphene, there have been tremendous improvements in the area of two-dimensional ( D) materials (e.g., graphene, topological insulators, and black phosphorus) based optoelectronics.eir unique and novel characteristics strongly promoted the developments of condensed-matter physics, device physics, photonics, electronics, optoelectronics, and so on.e purpose of this feature issue is to present the state of recent progresses in the eld, from fundamental physics (condensed-matter physics, device physics, and so on) to various applications of the emerging D materials.e feature issue covers various aspects of theoretical and experimental researches related to D materials based optoelectronics.Among plenty of submissions, we selected papers for publication in the special issue.e paper posted by S. Chen et al. demonstrates a homemade nonlinear response measurement system of D materials in sub-terahertz waveband.Using mutual frequency beating technology, they achieve the radiation of .THz wave with power up to mW.Based on this sub-terahertz source, they measure the nonlinear response of topological insulator.e paper by G. Li et al. studies the optical group delay in a modi ed Otto con guration with graphene surface plasmon.e optical group delay can be tuned obviously, even from negative to positive, with variety of means (Fermi energy, relaxation time of graphene, distance between the coupling prism, and graphene).e paper by Z.
