Plasmonic Y-splitters of High Wavelength Resolution Based on Strongly Coupled-Resonator Effects

Sharp Asymmetric Line Shapes in a Plasmonic Waveguide System and its Application in Nanosensor

“…1(d)]. It is very different from the previous reports that the Fano energy is dispersed in every resonators [13]- [16], [18], [19], [22], [26], [28], [30]- [35]. These properties make our structure more sensitive to the index variations compared with the previous reports [13], [22], [28], [30].…”

“…Therefore, combining the Fano-like response with MIM plasmonic structures would create the possibility of achieving ultracompact functional optical components for use in highly integrated optics [29]. The common characteristic of the papers reported about Fano resonances based on MIM waveguide system [13]- [16], [18], [19], [22], [26], [28], [30]- [35] is that the energy diffuses in every resonators, which makes the structures not very sensitive to the variation of refractive index of the material. Therefore, we need to find a new Fano forming structure, such that its energy can be concentrated mainly in a single resonator to obtain a high sensitivity of spectrum response to the index variations.…”

Multiple plasmon-induced transparencies in coupled-resonator systems

“…1(a). The calculated method can be seen in our previous work [17]. It was found that a narrow transmission peak emerges in the broadband transmission spectrum when the separation of the stub resonators is L 370 nm.…”

Theoretical analysis of plasmonic unidirectional propagation at visible frequency based on subwavelength waveguide

“…Recently, directional SPPs excitation and propagation by using MIM waveguides have received considerable interest. However, most of these researches mainly focus on the bidirectional SPP splitting in the MIM waveguides which usually consist of one input waveguide and two output waveguides [25][26][27]. The input and output waveguides can not be exchanged mutually for these schemes, and thus, their functions are limited.…”
