Review of Polarization Optical Devices Based on Graphene Materials

Abstract

Graphene has received extensive scholarly attention for its extraordinary optical, electrical, and physicochemical properties, as well as its compatibility with silicon-based semiconductor processes. As a unique two-dimensional atomic crystal material, graphene has excellent mechanical properties, ultra-high carrier mobility, ultra-wide optical response spectrum, and strong polarization dependence effect, which make it have great potential in new optical and polarization devices. A series of new optical devices that are based on graphene have been developed, showing excellent performance and broad application prospects. In this paper, the recent research progress of polarizers, sensors, modulators, and detectors that are based on the polarization characteristics of graphene is reviewed. In particular, the polarization dependence effect and broadband absorption enhancement of graphene under total reflection structure are emphasized, which enhance the interaction between graphene and light and then provide a new direction for research of graphene polarization devices.

Preliminary In Vitro Cytotoxicity, Mutagenicity and Antitumoral Activity Evaluation of Graphene Flake and Aqueous Graphene Paste

“…GO shows reduced thermal stability in comparison to the unmodified material but can interact with polar solvents or polymeric matrices, and for these reasons is the most-studied graphene form in biological research. The modification of both graphene and GO make it possible to obtain graphene-based materials (GBMs) which possess suitable properties for specific applications [5][6][7][8]. Graphene flake is of the most popular forms of graphene, and is used in conductive inks, nanofluids, supercapacitors, composites, and hybrid materials with practical utility in a wide range of applications [9]; it can also be obtained in the form of a stable dispersion [10].…”

Polarization-Independent Optoelectronic Modulator Based on Graphene Ridge Structure

“…At present, most of the current graphene-based optoelectronic modulators are polarization-dependent [18][19][20], which can only regulate a specific transverse magnetic (TM) or transverse electric (TE) mode. However, in the actual optical communication system, the polarization state of the optical signal changes randomly, in this case, the polarizationdependent optoelectronic modulators will inevitably cause polarization-sensitive loss [21][22][23]. Therefore, the research on the polarization-insensitive optoelectronic modulator is of practical significance.…”

Three-Dimensional Dirac Semimetal/Organic Thin Film Heterojunction Photodetector With Fast Response and High Detectivity

“…Since the successful preparation of graphene in 2004 [1], graphene has been widely studied due to its excellent carrier transport performance, unique two-dimensional (2D) energy dispersion, and stable electrical and optical properties [2][3][4]. At present, graphene has shown extremely high application value in many fields such as photoelectric detection, solar cell and optical modulator [5][6][7][8][9][10][11].…”
