“…The more the period number N, the more transmission peaks. This conclusion is the same as the calculations in the other studies [23,27]. This phenomenon can be explained by employing a simple physical model [27].…”

“…Therefore, based on equation (7), the dispersion curve of the structure (GD) N is also given in figure 5. As can be seen in figure 5, for the one-dimensional graphene photonic crystal (GD) N , similar to the calculation results in some literature [2,4,6,27], a series of passbands and stopbands appear in the calculated wavelength range.…”

Graphene photonic crystals have been attracting increasing attention due to their distinctive properties. In this work, the multichannel filtering performance of a one-dimensional graphene photonic crystal structure is theoretically investigated in the optical communication band. The graphene photonic crystal composed of a stack of alternating layers of dielectric material with high refractive index and graphene sheet. The influence of several structural parameters on the filtering performance of this structure was analyzed using the transfer matrix method. It is shown that the channel number and channel spacing of the multichannel filter can be adjusted by changing the period number and the dielectric constant and thickness of the high refractive index material. The multichannel filtering properties of this graphene structure have potential applications in wavelength division multiplexing systems.

“…6 for normal incidence. From there one can note that besides the low-frequency GIPBGs, there are also a much narrow another one at U ¼ 2, both of them, as conjectured, strongly dependent on the chemical potential, which can be tuned by a gate voltage [55]. They are shifted toward higher frequencies when the chemical potential increases, in a opposite way of the conventional Bragg's ordinary photonic band gaps, highlighted by the blue rectangles, which are not affected as predictable.…”

“…The tunable optical reflectivity, transmissivity, and absorptivity have been investigated in many graphene-based systems, such as graphene nanodisc arrays, 11,12 graphene nanoribbons, 13 alternating dielectric media with graphene layers sandwiched between them, [14][15][16] graphene-based Salisbury screens, 17 stacked graphene pairs or graphene photonic crystals, etc. [18][19][20][21][22] In a multilayer structural system, the optical transport properties and transmission are dependent on the number of dielectric and graphene layers, the dielectric space thickness, the incident angle, the incident light wavelength (or frequency) which is located in different graphene intraand/or inter-band optical transition regions, the surface plasmon-polaritons, and the transverse electric/transverse magnetic (TE/TM) modes. So many factors can be used to tune the optical properties of graphene-based dielectric structure systems which can meet the requirements of optoelectronic applications.…”

In this work, using the transfer-matrix method, the optical transport process is investigated, with graphene inserted into multilayer dielectric structures, theoretically and numerically in the THz regime. When the incident frequency is lower than the graphene Fermi energy, the optical intra-band transitions provide the main contribution to the graphene surface current. The absorptance can be enhanced to about 50% with only one graphene/dielectric layer in air. When increasing the number of dielectric layers coated with graphene, the absorption increases. Periodic absorption peaks are observed in multilayer structures. The positions of the absorption peaks as a function of the frequency and the incident angle are in accordance with the positions of the abrupt change in the reflection coefficient phase and of the imaginary solution of the Bloch wavevector in expanding periodic structures using Bloch theorem.
