To improve the performance of subwavelength refractive index and temperature sensors, this paper proposes a subwavelength metal-insulator-metal (MIM) waveguide structure consisting of a sawtooth U-shaped cavity and a rectangular cavity based on surface plasmon polaritons. The transmission spectrum of the system is simulated using the finite element method (FEM) and verified with multi-mode interference coupled-mode theory (MICMT). The results demonstrate excellent sensing characteristics for the system, with a refractive index sensitivity of 1300 nm/RIU, a figure of merit (FOM*) of 191.262, and a temperature sensitivity of 0.525 nm/℃. This indicates that the nano-plasma system is highly significant in refractive index and temperature sensing.

“…In this section, we discuss the application of the proposed elliptical waveguide in the paper as a pressure sensor. The optical pressure sensors based on SPP have myriad considerations due to their nano scale size, 29 – 31 which offers potential applications in biological and biomedical engineering. When a waveguide is deformed due to external pressure, the effective refractive index changes 32 , 33 .…”

We characterize the behavior of modes propagating along a hollow elliptical waveguide with lossy metamaterial cladding. The proposed metamaterial-dielectric elliptical waveguide supports surface-plasmon polariton (SPP) and hybrid ordinary-SPP modes in the operating frequency ranges. Previous studies on metamaterial-dielectric elliptical waveguides either ignore the effect of energy loss on the modes characteristics or employ approximate approaches to characterize modes behavior. Although some previous works include energy loss, they do not specify SPPs propagation versus hybrid-ordinary SPPs propagation in the operating frequency ranges. Here, we consider energy loss in the waveguide to eliminate errors resulting from neglecting the loss. Our waveguide structure facilitates SPP and hybrid ordinary-SPP modes propagation along the waveguide, has better energy confinement, and higher propagation length than previous results in the literature. In the elliptical waveguide, the propagation coefficient changes by changing the waveguide eccentricity; therefore, the elliptical nature of the studied waveguide facilitates its applications in pressure optical sensors.

“…The dielectric in the rectangular ring resonator and waveguides is air, and the metal material is silver. The fabrication of MIM waveguides and resonator is achievable with current technologies [48,49]. For example, MIM waveguides can be realized with the following steps: metal layer deposition, spin coating, E-beam writing, developing, chemical etching, and resist removal.…”

Integrated optical logic devices are essential building blocks for implementing all-optical arithmetic and logic unit. In this paper, an ultra-compact multifunctional optical logic device consisting of a rectangular ring resonator coupled with two parallel metal–insulator–metal waveguides is presented. The transmission characteristics of the structure are analyzed in detail via temporal coupled-mode theory. The finite-difference time-domain simulation results reveal that multiple logic functions can be implemented with the aid of the wavelength division multiplexing technique at different output ports. Specifically, all seven basic types of logic gates, half-adder, half-subtractor, and 2*4 decoder can be implemented by monitoring the transmission of through and drop ports at different wavelengths. More importantly, among these functions, six logic gates (OR, XNOR, NAND, NOR, XOR, and AND) and half-adder functions can be performed simultaneously; the NOT logic operation is performed with controllable output ports and selectable working wavelengths; the half-subtractor and 2*4 decoder functions can be operated simultaneously. The proposed logic device is characterized by a small area overhead, multifunctionality, fast response time, and ultrahigh-speed information processing. It may potentially be applied in on-chip universal and parallel photonic computing units.
