A new design of an S-band Thulium-doped modified Silica fiber co-doped with aluminum is presented. The design goal is high gain and low noise figure in the wavelength range of 1450 – 1520 nm. The optimization considers design parameters such as the cut-off wavelength, dopant concentration, waveguide structure, index profile and numerical aperture. These design parameters are optimized to achieve long...
Germanium and Silica co-deposition in MCVD process is studied with varying the flow ratio of GeCl4/SiCl4 at high temperature without phosphorus. The range of ratio is from 0.1 to 0.6 with temperature deposition 2100°C. The incorporation of germanium in silica matrix is deduced from the EPMA SEM-EDX. The experimental result is compared to theory such as thickness deposited layer and mole fraction of...
