“…Surface plasmon polaritons (SPPs) are waves propagated in the interface between the metal and dielectric, result from the interplay between the free electrons in metal and electromagnetic field which is incident on dielectric, and decaying exponentially in the direction perpendicular to the interface [1,2]. Surface plasmon polaritons have very good promising applications in the high density of optical component for integrated optical circuits and devices due to their removing of diffraction limit and light manipulation on subwavelength scales [1,3].…”

“…Although fibers make SPR sensors smaller and more flexible, the dimensions are still too large for sensing applications of lab on chip. Recently, metalinsulator-metal (MIM) plasmonic waveguides offering very high optical confinement and closer spacing to adjacent waveguides or structures have been proposed for diverse applications, such as MIM optical filers [25,26], electromagnetically induced transparency [27,28], Bragg gratings [29,30], and directional couplers [31,32]. Compared to other sensors, plasmonic sensors with MIM structures have an inherent advantage to achieve high integration.…”

A plasmonic refractive index sensor based on a circular resonator is proposed. With all three dimensions below 1 μm, the sensor has a compact and simple structure granting it ease-of-fabrication and ease-of-use. It is capable of sensing trace amounts of liquid or gas samples. The sensing properties are investigated using finite elements method. The results demonstrate that the plasmonic sensor has a relatively high sensitivity of 1,010 nm/RIU, and the corresponding sensing resolution is 9.9 × 10 −5 RIU. The sensor has a relatively high quality factor of 35, which is beneficial for identifying each transmission spectrum. More importantly, the sensitivity is not sensitive to changes of structure parameters, which means that the sensitivity of the sensor is immune to the fabrication deviation. In addition, with a transmittance of 5% at the resonant wavelength, this plasmonic structure can also be employed as a filter. In addition, by filling material like LiNbO 3 or liquid crystal in the circular resonator, this filter can realize an adjustable wavelength-selective characteristic in a wide band.

“…The diffraction limit of light has been a fundamental obstacle for reducing the dimensions of optical logic components to the scales of electronic devices in integrated circuits [2,3]. Surface plasmon polaritons (SPPs), the waves created on the surfaces of metals owing to the interaction of the electromagnetic fields in dielectrics and the free electrons in metals, have the most promising applications in the highly integrated optical circuits due to their ability to overcome the diffraction limit of light [4][5][6][7][8].…”

In this paper, we propose, analyze and simulate the performances of some new plasmonic logic gates in two dimensional plasmonic waveguides with nanodisk resonators, using the numerical method of finite difference time domain (FDTD). These gates, including XOR, XNOR, NAND, and NOT, can provide the highly integrated optical logic circuits. Also, by cascading and combining these basic logic gates, any logic operation can be realized. These devices can be utilized significantly in optical processing and telecommunication devices.
