The continued growth of the communications industry has caused interest in mode-division multiplexing (MDM) techniques to flourish in recent years. These techniques allow individual waveguide modes to be used as distinct ...

After decades of development, optical fiber technology has reached a high degree of sophistication and maturity, and currently serves as the backbone of today''s internet. Despite its technical versatility and capability, ...

Few-mode fibers (FMFs) and multimode fibers (MMFs) can provide much higher data-carrying capacities compared with single-mode fibers. But in order to achieve this goal, one must address the challenge of intermodal coupling ...

In this thesis, we demonstrate, theoretically, that, by depositing a regular fused-silica fiber with optical nonlinear molecules, strong and thermodynamically stable SHG can be obtained. Our experiments also provide strong ...

In recent years, nanoprobe-based devices have attracted significant attention and found a wide range of applications, including nanostructure imaging, single molecular detection, and physical, chemical, and biological ...
