We report on the fabrication and characterization of planar waveguides in an Er-doped tungsten-tellurite glass by implantation of 3.5 MeV N+ ions. Implantations were carried out in a wide fluence range of 1·1016 ÷8 ·1016 ions/cm2. Waveguides were

One of the main goals of the school and research system is the education of future scientists. However, being hard to figure out what the daily life of a scientist is, it is mandatory for a high school student to evaluate a future university career,

Surface tension induced whispering gallery mode (WGM) micro-resonators can be made in glass with very high quality factor Q. In fact, low losses amorphous glassy dielectrics can be easily shaped in high-surface-quality spheroids by thermal reflow. Si
