Characterization of Optical Coupling and Back-reflection of Few Mode Fibers
(Virginia Tech, 2015-09-01)
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 ...
Second Order Nonlinear Silica-Based Fibers and Microspheres
(Virginia Tech, 2009-05-08)
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, ...
Adaptive Mode Control in Few-Mode and Highly Multimode Fibers
(Virginia Tech, 2018)
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 ...
Silica Fiber with Large and Thermodynamically Stable Second Order Optical Nonlinearity
(Virginia Tech, 2008-04-24)
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 ...
Fabrication of Fluorescent Nanoprobes and Their Applications in Nanophotonics
(Virginia Tech, 2008-12-10)
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 ...
