Silicon Nano-Particles Doped Optical Fiber: Fabrication, Characterization, and Application

Glass: The carrier of light—Part II—A brief look into the future of optical fiber

“…Excellent examples of the former are nano-diamond in tellurite soft glasses and fibers [180][181][182][183] and silicon (Si) nanoparticles in CVD-derived silica. [184][185][186][187] Both examples exhibit unique or enhanced properties that are unquestionably of interest for future quantum communication, sensing, energy-harvesting and nonlinear optical systems.…”

“…In these cases, either the nanoparticle is sufficiently unreactive with the base glass so as to persist into the resultant fiber or undergoes some reaction still leading to a nanoscale heterogeneity that exhibits an optical response not present in a homogeneous glass. Excellent examples of the former are nano‐diamond in tellurite soft glasses and fibers 180‐183 and silicon (Si) nanoparticles in CVD‐derived silica 184‐187 . Both examples exhibit unique or enhanced properties that are unquestionably of interest for future quantum communication, sensing, energy‐harvesting and nonlinear optical systems.…”

Analysis of Spatially Doped Fused Silica Fiber Optic by Means of a Hamiltonian Formulation of the Helmholtz Equation

“…By means of the present formulation, the external perturbations can be conveniently engineered, such as each component of the electric field in the propagating mode is affected selectively. ese perturbations can be achieved by introducing selectively external materials to the fused silica matrix by different doping techniques [15]. Optical poling has been also one of the possible techniques to induce anisotropies and spatially modulated inhomogeneities to oxide glasses [16].…”
