A highly sensitive sensor based on two metal-insulator-metal waveguides coupled to an asymmetric hexagonal nano-ring resonator detecting cancerous cells is proposed. This novel design is utilized to facilitate the sensing of human cells. The sensing mechanism of the presented optical structure can act as a refractive index measurement in biological, chemical, biomedical diagnosis, and bacteria detection, which leads to achieving high sensitivity in the structure.

Hybridization of surface plasmons and photonic crystal resonators for high-sensitivity and high-resolution sensing applications.

In this paper, an optical refractive index (RI) sensor based on a hybrid plasmonic-photonic crystal (P-PhC) is designed. In the sensor's structure, some metallic rods are embedded in a rod-type photonic crystal (PhC) structure. Numerical simulations are performed based on the finite-difference time-domain (FDTD) method.

Design and simulation of a plasmonic density nanosensor for polarizable gases.

In this paper, an optical method of measuring the mass density of polarizable gases is proposed using a plasmonic refractive index nano-sensor. Plasmonic sensors can detect very small changes in the refracting index of arbitrary dielectric materials. However, attributing them to a specific application needs more elaboration of the material's refractive index unit's (RIU) relation with the introduced application.

Analysis and investigation of temperature and hydrostatic pressure effects on optical characteristics of multiple quantum well slow light devices.

This paper represents the influences of temperature and hydrostatic pressure variations on GaAs/AlGaAs multiple quantum well slow light systems based on coherence population oscillations. An analytical model in non-integer dimension space is used to study the considerable effects of these parameters on optical properties of the slow light apparatus. Exciton oscillator strength and fractional dimension constants have special roles on the analytical model in fractional dimension.

Method proposing a slow light ring resonator structure coupled with a metal-dielectric-metal waveguide system based on plasmonic induced transparency.

We demonstrate the analogue of electromagnetically induced transparency (EIT) in a metal-dielectric-metal (MDM) plasmonic waveguide. Plasmonic induced transparency is a method similar to EIT. In this paper, a plasmonic MDM waveguide is proposed by using an ellipse shaped side-coupled ring resonator and simulated by finite difference time domain.

Electro-plasmonic 2 × 2 channel-routing switch arranged on a thin-Si-doped metal/insulator/semiconductor/metal structure.

Plasmonics as a new field of chip-scale technology is the interesting substrate of this study to propose and numerically investigate a metal/insulator/semiconductor/metal (MISM)-structure 2×2 plasmonic routing switch. As a planar subwavelength arrangement, the presented design has two npn-doped side-coupled dual waveguides whose duty is to route the propagating surface plasmon polaritons through the device. Relying on the MISM structure, which has a MOS-like thin-film arrangement of typically 45 nm doped silicon covered by a layer of 8 nm thick HfO(2) gate insulator, the routing configuration is electrically addressed based on the carrier-induced plasma dispersion effects as an external electro-plasmonic switching control.

Design and investigation of N-type metal/insulator/semiconductor/metal structure two-port electro-plasmonic addressed routing switch.

Relying on the new field of technology, plasmonics, we have proposed and investigated an N-type metal/insulator/semiconductor/metal (MISM)-based 1×2 plasmonic routing switch. However, the MISM structure has a 50 nm thick silicon core waveguide accompanied by a thin-film HfO(2) gate insulator, the electro-plasmonic addressing of the structure guides and routes the surface plasmon polaritons on a subwavelength regime. FEM-based electromagnetic simulations are prepared at a telecom wavelength of λ=1550  nm.

A rate equations approach has been used in which parameters are derived from simulation results of the plasmonic amplifier (Silvaco/ATLAS).

Design and simulation of an electrically pumped Schottky-junction-based plasmonic amplifier.

We have investigated an amplifier which operates on surface plasmon polaritons (SPPs). A semiconductor is considered instead of dielectric since its interface with metal can support transverse-magnetic-polarized SPP propagation. A T-shaped cross section for the analyzed waveguide is considered.

Design and simulation of a nanoscale electro-plasmonic 1 × 2 switch based on asymmetric metal-insulator-metal stub filters.

A compact nanoscale electro-plasmonic 1 × 2 switch based on asymmetrical metal-insulator-metal stub filters is introduced. The structure is designed and analyzed based on the transmission line method, and the switching operation of the device is numerically simulated and verified by the finite element method. It is found that by adjusting the length of the stubs on each output branch of the structure the surface plasmon polaritons (SPPs) are guided to only one of the output ports.

This paper demonstrates the effects of applying magnetic and electric fields and physical dimensions alterations on AlGaAs/GaAs multiple quantum well (QW) slow light devices. Physical parameters include quantum well sizes and number of quantum wells. To the best of our knowledge, this is the first analysis of the effects of both applying magnetic/electric fields and physical parameters alterations and the first suggestion for matching the prefabrication and post fabrication tuning of the slow light devices based on excitonic population oscillations.
