Self-Aligned Emission of Distributed Feedback Lasers on Optical Fiber Sidewall
This article assembles a distributed feedback (DFB) cavity on the sidewalls of the optical fiber by using very simple fabrication techniques including two-beam interference lithography and dip-coating. The DFB laser structure comprises graduated gratings

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 ...

Finite size effects in the dynamics of glass-forming liquids [PDF]
We present a comprehensive theoretical study of finite size effects in the relaxation dynamics of glass-forming liquids. Our analysis is motivated by recent theoretical progress regarding the understanding of relevant correlation length scales in liquids

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 ...

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 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

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 in Quantized High Quality Films [PDF]
The effect of coupling of quantized modes on transport and localization in ultrathin films with quantum size effect (QSE) is discussed. The emphasis is on comparison of films with Gaussian, exponential, and power-law long-range behavior of the ...
