AbstractAbstract
[en] Ion implantation may be used to change optical properties of glass and produce optical waveguides. If glass substrate is also a laser host material, this can lead to waveguide laser formation. A variety of laser glasses (silicate, phosphate, fluoride) have been studied in detail. In general the refractive index decreases in both electronic and nuclear interaction regions The percentage change appears to be from 0.4-0.8% in electronic interaction region, and 0.8-1.2% in nuclear collision region, which is sufficient to define a waveguide. The refractive index profile is influenced by several parameters, such as type of ion, ion energy, ion dose, and temperature of implant. Also annealing studies have been made to reduce loss, to check the thermal stability, and to study recovery of the index change. Overall the indications are that ion implanted laser glass waveguides are feasible. (author). 13 refs., 4 figs., 1 tab

AbstractAbstract
[en] The paper discusses the analysis of tapered hybrid composite microfibers based on a metal-core and dielectric-cladding composite material system. Its advantages over the pure metal tips conventionally used, are the inherent enhanced environmental robustness due to inert borosilicate cladding and the capability of multiple excitation of the tapered nanowire through the length of the fiber due to the enabled total internal reflection at the borosilicate/air interface. Simulations through finite element method (FEM) have demonstrated an improved field enhancement at the tapered region of such microfibers. Furthermore, experimental results on tapering in copper based microfibers together with light coupling and propagation studies will be demonstrated revealing the potential for the development of plasmonic devices for sensing applications.
