“…Moreover, in the frequency ranges of terahertz and far infrared, the graphene sheet has negligible loss and absorption compared to metals. In recent years, the use of photonic crystals constructed by graphene to realize optical filters has attracted many researchers' interest [1][2][3][4][5][6][7][8][9][10][11][12][13]. Similar to the photonic crystals composed of traditional dielectrics, graphene photonic crystals generally achieve filtering by using a certain defect structure [1][2][3][4][5][6][7][8][9][10].…”

“…Based on graphene, researchers have also proposed some other photonic crystal structures to realize optical filters. Sattarian et al proposed a one-dimensional hybrid graphene-photonic crystal structure to obtain a high transmission threecolor filter [11]. Saleki et al [12] and Silva et al [13] respectively studied the transmission properties of onedimensional Thue-Morse and Octonacci quasi-periodic graphene photonic crystals, and found that these two quasi-periodic structures can be used as polarizing beam splitters or polarizing filters.…”

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.

“…Typical examples are PhC enhanced light harvesting, [ 10–12 ] PhC enhanced catalysis, [ 13,14 ] PhC enhanced Raman spectroscopy, [ 15–19 ] PhC enhanced fluorescence spectroscopy, [ 17,20,21 ] PhC enhanced upconversion, [ 22,23 ] etc. [ 24–26 ] More specifically, Wen Xu and Hongwei Song reported that with the guidance of theoretical simulation, the plasmonic effect combined PhC effect enhanced the fluorescence of CsPbCl 3 by ≈150‐fold. [ 27 ] Another example is ≈130 and 350 times enhancements for green and red luminescence were observed in a PhC embedded with upconversion nanoparticles structure than the one without PhC.…”

Photonic crystals (PhC) can be elaborately tailored to enhance the electromagnetic properties of materials and are drawing increasing attention in recent years. However, there is no sufficient theoretical framework to optimize photonic crystal designs for electric enhancement. A comprehensive theoretical model is presented to illustrate Au/Ag photonic crystal enhancement on electric fields and obtain a group of optimal photonic crystal parameters after large number of statistics and parameter scans. The second and deeper layers of PhC only contribute to both 5% extinction and absorption in the far-field, and there is almost no difference in |E| max among different layers with the coefficient variation at ≈1%. Furthermore, increment of both lattice constants and NP diameters can trigger dramatic changes in |E| max , and the maximal |E| max derived from 190 nm AuNP (nanoparticle)-Au PhC with the lattice constant of 560 nm. This structure is 47.7, 7.39, 4.63, and 2.69 times that of AuNP incorporated silica wafer, silicon wafer, Ag wafer, and Au wafer, respectively. The strong electric field enhancement attributes to not only the plasmonic effect but also the photonic crystal enhancement effect.The simulation procedures open the possibility of precise photonic crystal structure design and pave the way for various electric field enhancement applications.
