“…The terms of 'surface plasmon' and 'polariton' are respectively involved charge motion in highly conductive matter, and electromagnetic waves in the dielectric or vacuum. The materials which are frequently used in plasmonic structures are typically metals such as silver and gold, which are exploited in various applications such as filters [1][2][3], demultiplexers [4][5][6], sensors [7][8][9], and switches [10][11][12].…”

In this study, a tunable graphene plasmonic filter and a two-channel demultiplexer are proposed, simulated, and analyzed in the mid-infrared (MIR) region. We discuss the optical transmission spectra of the proposed cross-shaped resonator and the two-channel demultiplexer. The transmission spectra of the proposed MIR resonator are tunable by change of its dimensional parameters and the Fermi energy of the graphene. Our proposed structures have a single mode in the wavelength range of 5-12 µm. The minimum full width at half maximum (FWHM) and the maximum transmission ratio of the proposed resonator respectively reached 220 nm and 55%. Simulations are performed by use of three-dimensional finite-difference time-domain (3D-FDTD) method. Coupled mode theory (CMT) is used to investigate the structure theoretically. The numerical and the theoretical results are in good agreement. The performance of the proposed two-channel demultiplexer is investigated based on its crosstalk. The minimum value of crosstalk reaches −48.30 dB. Our proposed structures are capable of providing sub-wavelength confinement of light waves, useful in applications in MIR region.

“…Similar all-optical switching arrangements are based on Mach-Zehnder interferometry [101,102]. Other schemes make use of semiconductor nanoparticles [103][104][105], nanoplasmonic waveguides [106][107][108][109], fiber Bragg gratings [110][111][112] or nanocavities in photonic crystals to strongly enhance optical nonlinearities [113,114]. Moreover, based on irradiation of rubidium vapor, there is a development that uses counter-propagating laser beams to induce an optical pattern that rotates on application of a switching laser [115].…”

The theory of non-resonant optical processes with intrinsic optical nonlinearity, such as harmonic generation, has been widely understood since the advent of the laser. In general, such effects involve multiphoton interactions that change the population of each input optical mode or modes. However, nonlinear effects can also arise through the input of an off-resonant laser beam that itself emerges unchanged. Many such effects have been largely overlooked. Using a quantum electrodynamical framework, this review provides detail on such optically nonlinear mechanisms that allow for a controlled increase or decrease in the intensity of linear absorption and fluorescence and in the efficiency of resonance energy transfer. The rate modifications responsible for these effects were achieved by the simultaneous application of an off-resonant beam with a moderate intensity, acting in a sense as an optical catalyst, conferring a new dimension of optical nonlinearity upon photoactive materials. It is shown that, in certain configurations, these mechanisms provide the basis for all-optical switching, i.e., the control of light-by-light, including an optical transistor scheme. The conclusion outlines other recently proposed all-optical switching systems.

We propose a metal-insulator-metal (MIM) waveguide structure in which the plasma-induced transparency (PIT) effect is based. Using the finite-difference in time domain (FDTD) method, the designed structure was simulated in two dimensions. It obtains both narrowband PIT peaks, both with more than 90% absorption. In addition, we use the Kerr material filled in the cavity for tuning, and we can find that the transmission spectrum shifts with increasing pump light intensity. The proposed structure can be applied to filter. The proposed structure has important prospects for application in integrated optical devices.
