“…From figure 3, we also notice that the channel spacing is large in the long wavelength band, while it is relatively small in the short wavelength band. This situation has also appeared in the calculation results of some literature [14,29]. From figure 5, we can see why this has happened.…”

“…Therefore, under the same conditions, the size of the filter device we constructed will be relatively small. Compared with the optical filter constructed by traditional dielectric materials [29,30], the high refractive index material used here also contributes to the reduction of device size. In conclusion, the multichannel filter structure discussed in this paper has the advantage of small device size, while its performance can meet the relevant requirements.…”

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.

Optoelectronics, often known as photon-based electronics, is well recognised for being more effective than conventional electronics for communication. To create a superfast computer, several devices have previously been developed in the field of all optical computing systems. Here, we have put forth an all-optical 2:1 multiplexer with the usage of nonlinear material exhibiting a strong ac Kerr effect and 2:1 Multiplexer (MUX) based all optical -photonic switches - NOT, OR, AND, NAND, NOR etc. The sole method for building combinational logic circuits is to utilise MUX. This work is made simpler by the Shannon decomposition theorem than by other approaches. In this study, input and output are expressed as the presence of a light signal with a prefixed intensity as binary 1 and the absence of a light signal as binary 0 using an intensity-based all-optical device and positive logic. Since the system is entirely optical, our current design enables very-high speed (terahertz) computation, which is not possible with typical semiconductor electronic switches. Validation through mathematical computations-based PYTHON simulations establishes the efficacy of the proposed approach. This research holds promise for applications in industrial and commercial contexts, offering enhanced performance and versatility.
