Step-index Si-Ge-core silica-cladded optical fibers
2020 IEEE Research and Applications of Photonics in Defense Conference, RAPID 2020 - Proceedings
Si-Ge alloy-core silica-cladded fibers were drawn at a low temperature to minimize impurity diffusion. The elemental segregation in the as-drawn fibers was overcome by a thermal treatment. The transmission losses of the fibers were calculated as 28 dB/cm at 6.1 μm wavelength.
