Modal Coupling in Presence of Dry Friction
In this paper, we analyze the behavior of a single pad system in the presence of dry friction. The goal is to investigate the path that leads a stable mechanical system to unstable behavior.

Coupling between guided modes of two parallel nanofibers
We study the coupling between the fundamental guided modes of two identical parallel nanofibers analytically and numerically. We calculate the coefficients of directional coupling, butt coupling, and self coupling as functions of the fiber radius, the ...

Mode-Coupling Induced Crosstalk Optimization in a Graded-Index Six-Mode Fiber
We thoughtfully investigate the feasibility of reducing the mode-coupling caused crosstalk by optimizing the practical parameters of the few-mode fiber (FMF), based on the linear coupling theory. According to our simulation results, the low crosstalk FMF

Mode Coupling Properties of the Plasmonic Dimers Composed of Graphene Nanodisks
The electromagnetic properties of the plasmonic dimer composed of coupled graphene nanodisks are numerically investigated in this paper. The results demonstrate that the degeneracy of the plasmonic modes of the dimer is lifted when the coupling is ...

Efficient slow-light coupling in a photonic crystal waveguide without transition region [PDF]
We consider the coupling into a slow mode that appears near an inflection point in the band structure of a photonic crystal waveguide. Remarkably, the coupling into this slow mode, which has a group index n(g) > 1000, can be essentially perfect without ...

High Efficiency Coupling Technology of Silicon Photonic Modulator and Single-Mode Optical Fiber
Due to the small mode field of silicon photonic chips, the large coupling loss is a road-blocker for their applications. In this work, the coupling efficiency between a silicon photonic modulator chip and a single-mode optical fiber is investigated.

Mode coupling control in a resonant device: application to solid-state ring lasers [PDF]
A theoretical and experimental investigation of the effects of mode coupling in a resonant macro- scopic quantum device is achieved in the case of a ring laser. In particular, we show both analytically and experimentally that such a device can be used as

Dynamics of the pedestal in the recovery phase in EAST type-I ELM plasmas
In the Experimental Advanced Superconducting Tokamak high-confinement mode plasmas, a low-frequency n = 1 magnetic coherent mode with frequency f = 20–50 kHz and a high-frequency mode with electromagnetic characteristics (HFEM, f ∼ 280 kHz) have been ...
