Guided Bloch Surface Waves on Ultrathin Polymeric Ridges

We present a direct evidence of Bloch surface waves (BSWs) waveguiding on ultrathin polymeric ridges, supported by near-field measurements. It is demonstrated that near-infrared BSWs sustained by a silicon-based multilayer can be locally coupled and guided through dielectric ridges of nanometric thickness with low propagation losses. Using a conventional prism-based configuration, we demonstrate a wavelength-selective BSW coupling inside and outside the ridge. Such a result can open interesting opportunities in surface wave-mediated sensing applications, where light could be selectively coupled in specific regions defined by nanometric reliefs.KEYWORDS Surface electromagnetic waves, near-field optical microscopy B loch surface waves (BSW) are either TE-or TMpolarized surface modes that can be sustained by truncated stacks of periodically arranged dielectric layers. 1,2 Although BSWs have been known for more than thirty years, they have been recently reconsidered as an alternative to surface plasmon polaritons (SPP), 3 in particular in sensing applications. [4][5][6] Until now, a number of far-field and near-field investigations have been conducted on the coupling of BSW on flat 7-9 and corrugated planar structures. [10][11][12] Here we demonstrate that near-infrared BSWs can be selectively prism-coupled and efficiently guided through an ultrathin polymeric ridge waveguide having thickness < λ/10 realized onto a silicon nitride multilayer. Besides being wavelength scalable and fully compatible with the actual fabrication technologies of integrated photonic and plasmonic structures, the proposed hybrid organic/inorganic structure can provide disruptive opportunities in waveguide-based biosensing schemes, (see, e.g., ref 13) in which the chemical specificity of the sensor might be implemented by functional molecule layers patterned as waveguides with nanometric thickness.In the past decade, a large number of issues connected to the guiding of electromagnetic surface waves (mostly SPP) on a subwavelength scale have been addressed by one branch of plasmonics. 14 Plasmonic waveguides according to different geometries have been proposed mainly for gaining strong (lateral) field confinement while maintaining low propagation losses in view of a high-density packing of integrated photonic circuitry. 15 In addition to guiding mechanisms based on ultrathin metallic membranes, 16 nanoparticles chains, 17,18 nanowires on dielectric substrates, 19 dielectric nanocylinders on metallic films, 20 or V-grooves in metal surfaces, 21 the most popular plasmonic waveguide configurations are constituted by metal-insulator-metal (MIM) 22,23 or insulator-metal-insulator (IMI) 24 structures. Among the latter, we recall the so-called dielectric-loaded surface plasmon polariton waveguides (DLSPPW), 25 in which a dielectric stripe is deposited onto a flat metallic film. The dielectric cladding is thick enough to confine SPP within the ridge, therefore lowering the propagation losses as well as the sensitivity upon external perturbat...

“…SP waveguides based on insulator-metal-insulator (IMI) waveguides have been studied extensively [9,10]. However, metal-insulator-metal (MIM) SP waveguides have higher confinement factors and closer spacing to adjacent waveguides [11,12] and have been proposed for a lot of applications [5][6][7][8].…”

Investigation of Second Harmonic Generation in Asymmetric Metal-Insulator-Metal Plasmonic Waveguides

2015

In this study, the second harmonic generation in metal-insulator-metal (MIM) plasmonic waveguides was investigated for both symmetric and asymmetric structures. Nonlinear processes such as second harmonic generation (SHG) are important for applications such as switching and wavelength conversion. In this study, it was shown that field enhancement in asymmetric metal-insulator-metal waveguides can result in large enhancement of SHG. Thus, a structure consisting of a MIM waveguide filled with lithium niobate and sandwiched between two same metals was first considered in this study. Thereafter, two different metals on both sides of the waveguide were used. It was shown in this study that this asymmetric device results in more than two orders of magnitude enhancement in SHG compared to a uniform slab of lithium niobate. For such structures, the field enhancement is due to the squeezing of the optical power from the wavelengthsized dielectric waveguide to the deep sub-wavelength MIM waveguide. So, the novelty of this paper is proposing a metalLiNbO3-metal nanostructure with different top and bottom metals as plasmonic waveguides. Two different metals, gold and silver, are used as the metals of plasmonic waveguides, and the SHG is investigated in different structures. The interaction between interfering surface plasmonic polariton modes is studied. It is found that compared to the conventional symmetric metal-insulator-metal plasmonic waveguides, the asymmetric structure with different metals, silver-LiNbO 3 -gold, has higher SHG and longer propagation distance.

“…Three kinds of typical nanophotonic waveguides have been developed in the past years, which includes nanophotonic wires (strip nano-waveguide) [1,2], photonic-crystal waveguides [3] and nanoplasmonic waveguide [4][5][6][7][8][9][10][11][12][13][14][15][16]. The former two nanophotonic waveguides, which utilize nano-structures with ultra-high index contrast, cannot be beyond the diffraction limit.…”

Recently hybrid plasmonic waveguides have been becoming very attractive as a promising candidate to realize next-generation ultra-dense photonic integrated circuits because of the ability to achieve nano-scale confinement of light and relatively long propagation distance. Furthermore, hybrid plasmonic waveguides also offer a platform to merge photonics and electronics so that one can realize ultra-small optoelectronic integrated circuits (OEICs) for high-speed signal generation, processing as well as detection. In this paper, we gave a review for the progresses on various hybrid plasmonic waveguides as well as ultrasmall functionality devices developed recently.
