Decoupling co-existing surface plasmon polariton (SPP) modes in a nanowire plasmonic waveguide for quantitative mode analysis

Nanowires for Photonics

“…From last decades, although Ag nanowire-based plasmonic waveguides have been intensively studied, the measured propagation lengths have been shown significant discrepancies based on their diameter and the measurement conditions. 111,[115][116][117] To elucidate this inconsistency, a chemically-grown Ag nanowire-based SPP modes have been discovered by using a tapered optical fiber tip touching to a suspended Ag nanowire. 115 For optical elements integration, a structure-dependent SPPs loss such as bending loss has to be also considered.…”

3D Multifunctional Composites Based on Large‐Area Stretchable Circuit with Thermoforming Technology

“…Through materials and structure innovation, the circuits become stretchable, deformable, and conformable to curvilinear surfaces, enabling a spectrum of applications such as stretchable sensors and actuators, transparent conductors, lighting, and energy devices . Various types of stretchable nanomaterials, such as carbon nanomaterials and metal nanowires have been synthesized and integrated to elastomeric polymer matrix for stretchable circuits. Despite their superior mechanical properties and potential to achieve transparent stretchable circuits, so far it has been a struggle to deliver high enough conductivities compared to structure engineered stretchable circuits.…”

“…[3][4][5][6] They were dispersed in a polymer matrix to form conductive percolating networks as distributed sensors in situ to evaluate the strain, stress, damage, and temperature for self-sensing and on-line structural health monitoring applications. [20][21][22] Various types of stretchable nanomaterials, such as carbon nanomaterials [23][24][25] and metal nanowires [26][27][28] have been synthesized and integrated to elastomeric polymer matrix for stretchable circuits. Nextgeneration composites, however, should not only encompass sensing capabilities but also be equipped with other functionalities such as lighting, computation, and communication elements, as illustrated in Figure 1.…”

Theoretically Analyzed Optical Property of Silver Nanowire on a SiO2 Layer

“…They found that the coupling distance, size of structure and the dielectric environment have important effects on SPPs. Therefore, many kinds of model, have been investigated in recent literatures through both the simulation and experiment methods, such as nano-particles [12], [13], nanowires [14]- [16] and so on. In the structure we talked about before, the nanowires have important applications in photonic devices because of the small mode volume, localized resonant modes, and long photon life-times.…”
