“…An approach of using concepts of mott phase change material in PhCs-based structure responsible for the shifting of the optical bandgap is investigated in [46] and using polymer waveguides with high thermos-optic and electro-optic in [47]. Similarly, a 3D Si-opal composite is reported in [48], with a pump-probe technique in [49], and 1D graphene-based plasmonics crystals in [50], to efficiently pronounce the effects of optical switching. Apart from these, using two PhC-cavities within one arrangement is reported in [51], using a waveguide between them.…”

Optical switching is an essential part of photonic integrated circuits and the focus of research at the moment. In this research, an optical switch design working on the phenomenon of the guided-mode resonances in 3D photonic crystals-based structure is reported. The optical-switching mechanism is studied in a dielectric slab-waveguide-based structure operating in the near-infrared range in a telecom window of 1.55 µm. The mechanism is investigated by interference of two signals, i.e., the data signal and the control signal. The data signal is coupled into the optical structure and filtered utilizing guided-mode resonance, whereas, the control signal is index guided in the optical structure. The amplification or de-amplification of the data signal is controlled by tuning the spectral properties of the optical sources and structural parameters of the device. The parameters are optimized first using a single-cell model with periodic boundary conditions and later in a finite 3D-FDTD model of the device. The numerical design is computed in an open-source Finite Difference Time Domain simulation platform. Optical amplification in the range of 13.75 % is achieved in the data signal with a decrease in the linewidth up to 0.0079 µm and a quality factor of 114.58. The proposed device presents great potential in the field of photonic integrated circuits, biomedical technology, and programmable photonics.

“…Compared with the traditional PTIs, it offers better performance such as tight field confinement, relatively low propagating loss, and flexible tunability [10,28]. Moreover, Monfared et al have achieved the photoelectric switch operation by utilizing the unique optical properties of SPPs supported by graphene [30][31][32] Recently, Dehghan et al reported the graphene periodic lattice, which causes plasmonic modes to absorb a specific Terahertz frequency band and minimize transmission [33]. Graphene-supported SPPs have been recognized as a promising two-dimensional material for a wide range of applications such as transparent electronics, gate modulators, photocatalysts, and more [25,29,[34][35][36][37][38].…”

In this article, three categories of the edge states in the honeycomb lattice are investigated theoretically by using the effective tight binding Hamiltonian. The edge-bulk corresponding dispersions of zigzag, bearded, and armchair edge states analytically. The actual edge-bulk corresponding and the light field distribution of the graphene plasmonic crystals are obtained by solving Maxwell equations with boundary conditions, which are in good agreement with the analytical results. The proposed plasmonic structures provide guidance for designing the frequency range dependent property of topological structures, and show the potential applications in topological robust devices.
