“…Since a wavelength dependence analysis has to be carried out for this structure, one should bear in mind that the dielectric constants of the materials involved are also wavelength dependent. Therefore, the effective indices n eff1, 3 and n eff2 obtained with the EIM must carry the wavelength dependence of the materials utilized in the structure. We have used the Sellmeier equations available in [36,37] for the refractive indices of SiO 2 and As 2 S 3 , and a polynomial fit of the experimental data from [38] for the relative permittivity of Ag.…”

“…Thus, by changing the structure of the surface of a metal, the properties of SPPsin particular their interaction with light-can be manipulated, offering potential for the development of new types of photonic devices. Many approaches have been suggested for this purpose, particularly based on the metal-insulator-metal (MIM) configuration, such as tooth-shaped structures [1][2][3][4][5][6], gap-based filters [7][8][9][10], and, more recently, tilted coupled resonators for wavelength selection purposes [11]. MIM structures provide excellent field confinement, at the expense of shorter propagation distances and low quality factors Q (except for the structures in [11] which have achieved the largest Q for MIM-based geometries).…”

A long-range surface plasmon-polariton waveguide ring resonator as a platform for (bio)sensor applications Journal of Optics, Bristol : Institute of Physics -IOP ,v. 13, n. 11, p. 115001-1-115001-7, Nov. 2011 http://www.producao.usp Abstract A ring plasmon-polariton resonator has been investigated and proposed as a promising platform for (bio)sensor devices. Many applications related to sensitive, miniaturized, and lab-on-a-chip devices can be realized with the structure proposed in this work. This structure consists of a rib-type ring configuration employing a metallic film sandwiched by dielectric layers. The adopted operating wavelength is λ = 1550 nm. Our theoretical investigation shows that the proposed structure not only has low loss, and consequently a long propagation distance (2.17 mm), but also a good lateral field confinement and a quality factor Q tot ≈ 1146. This high quality factor is essential for sensing applications where the conductivity of analyte mixtures is allowed to vary.

“…Due to its unique characteristics including the strong confinement of optical field in nano-scale gaps, the high sensitivity of its transmission characteristics to the waveguide structures, and the facility of its fabrication, the MIM waveguide has attracted a great deal of effort in the fields of waveguide couplers [13], [14], sub-wavelength scale light confinement [15], [16], wavelength filters [17], [18], and integrated optical devices [19], [20]. Recently, numerous studies have been taken out to investigate the plasmonic resonators such as the plasmonic stubs [21]- [23], nano-capillary resonators [24], side-coupled FabryPerot [25], [26], high-performance wavelength demultiplexer [27], ultrafast all-optical switching [28], tunable high-channelcount bandpass filters [29], and slot cavities [30]- [34]. Ring resonator structure with circular or rectangular geometries is the mostly commonly used type of plasmonic resonators [35]- [40].…”

Abstract-We proposed a nanoplasmonic optical filtering technique based on complementary split-ring resonator structures. Interestingly, the proper plasmonic modes of the nanoring in the side-coupled arrangement can be selected and excited by the proposed structures. It is observed that the non-integer modes can be excited due to the presence of a metallic nano-wall as well as the integer modes. Furthermore, the numerical results indicate that the optical transmission spectrum of the investigated filter can be efficiently modified and tuned by manipulation either the position or the width of the employed nano-wall inside the metal-insulator-metal ring. The antinodes of the magnetic field of these modes, located on the symmetry plane of the proposed structures, can be manipulated by the position of the wall. Additionally, these modes, in particular the fundamental mode, are highly sensitive to the nano-wall dimensions. It indicates that the proposed nanofilter is a promising candidate as a tunable filter in nanophotonics applications.
