Band-stop filter based on a metal/insulator-disk array/metal structure

We describe a band-stop filter based on a periodic dielectric-disk array inserted into a metal–insulator–metal (MIM) waveguide. We use finite-difference time-domain (FDTD) methods to study the characteristics of our proposed structure. The results show that there is a flat stop band in the transmission spectrum, in which the transmission is close to zero. The central wavelength of the filter can be controlled by adjusting the lattice constant of the disk array. We discuss the maximum bandwidth and provide a set of parameters suitable for designing a band-stop filter that has a flat stop band-width of approximately 400 nm and a superior on/off ratio. Our structure has potential applications in the design of nanoscale optical devices.

In this paper, we have numerically investigated a novel kind of ultra-compact wavelength demultiplexing (WDM) in high-confined metal–insulator–metal (MIM) plasmonic waveguides. It is found that the drop transmission efficiency of the filtering cavity can be strongly enhanced by introducing a side-coupled cavity in the MIM waveguide. The theoretical analysis is verified by the finite-difference time-domain simulations. Through cascading the filtering units, a highly effective triple-wavelength demultiplexer is proposed by selecting the specific separation between the two coupled cavities of filtering units. Our results may find potential applications for the nanoscale WDM systems in highly integrated optical circuits and networks.

Abstract In this paper, we present a proposal for compact photonic wavelength filtering and 3-dB wavelength splitting device based on nanoplasmonic metal-insulator-metal structure. The working performance of the device has been accurately simulated using the temporal coupled-mode theory. We use a numerical simulation method of eigenmode expansion propagation for the overall design process. We show that the transmission efficiency of the drop filter can be significantly enhanced by applying specifically optimization of nanostub waveguide. The proposed structure has potential applications in highly efficient ultra-compact integration circuits as well as in optical communication systems at nanoscale.

Mim Waveguide

Metal-insulator-metal (MIM) silicon based nanostub structures have been designed and analyzed using the finite difference time-domain (FDTD) technique. An analytic model is discussed which is based on the resonance theory. Numerical results show double and single narrow band transmissions for small and long lengths of nanostub, respectively. The transmission band of the structure is controlled by varying the width and the length of the nanostub. These MIM nanostub structure can have potential applications in nanoscale high density photonic integrated circuits (PICs).

Difference Time

We investigate the strong coupling phenomenon between a circular cavity and a rectangular cavity based on a metal–insulator–metal (MIM) structure. Finite difference time domain method is employed to well describe the strong coupling phenomenon and the simulation results show that two splitting peaks are observed in our proposed structure, while only one resonant peak is found in MIM structure involving only a circular cavity. The coupling between the circular cavity and the rectangular cavity is manipulated by the geometry of the cavities and the symmetry of the whole structure. An asymmetric lineshape of the transmission spectrum is observed with a narrow linewidth and a deep valley, which has potential applications in plasmon sensor.

A tunable demultiplexer with three output channels infiltrated by liquid crystal (LC) is presented, which is based on a metal-insulator-metal (MIM) waveguide. The operating frequencies of the three output channels can be tuned simultaneously at will by changing the external bias electric field applied to the LC. By analyzing the Fabry-Pérot (FP) resonance modes of the finite-length MIM waveguide both theoretically and numerically, the locations of the three channels are delicately determined to achieve the best demultiplexing effects. Terahertz (THz) signals input from the main channel can be demultiplexed by channels 1, 2 and 3 at 0.7135 THz, 1.068 THz and 1.429 THz, respectively. By applying an external electric field to alter the tilt angle of the infiltrating LC material, the operating frequencies of channels 1, 2 and 3 can be relatively shifted up to 12.3%, 9.6% and 9.7%, respectively. The designed demultiplexer can not only provide a flexible means to demultiplex signals but also tune operating bands of output channels at the same time.

Mim Waveguide

In this study, a nano-refractive index sensor is designed that consists of a metal–insulator–metal (MIM) waveguide with a stub-1 and an orthogon ring resonator (ORR) with a stub-2. The finite element method (FEM) was used to analyze the transmission characteristics of the system. We studied the cause and internal mechanism of Fano resonance, and optimized the transmission characteristics by changing various parameters of the structure. In our experimental data, the suitable sensitivity could reach 2260 nm/RIU with a figure of merit of 211.42. Furthermore, we studied the detection of the concentration of trace elements (such as Na+) of the structure in the human body, and its sensitivity reached 0.505 nm/mgdL−1. The structure may have other potential applications in sensors.

We studied the metal-insulator-metal square ring resonator design incorporated with nano-dots that serve to squeeze the surface plasmon wave in the cavity of the ring. The E-field enhances at the boundaries of the nano-dots providing a strong interaction of light with the surrounding medium. As a result, the sensitivity of the resonator is highly enhanced compared to the standard ring resonator design. The best sensitivity of 907 nm/RIU is obtained by placing seven nano-dots of radius 4 nm in all four sides of the ring with a period (ᴧ)= 3r. The proposed design will find applications in biomedical science as highly refractive index sensors. Full Text: PDF References:Z. Han, S. I. Bozhevolnyi.
