CO2 laser annealed SiGe core optical fibers with radial Ge concentration gradients
Wu, Wei; Balci, Mustafa H.; Song, Seunghan; liu, chunxin; Fokine, Michael; Laurell, Fredrik; Hawkins, Thomas A.; Ballato, John; Gibson, Ursula (Peer reviewed; Journal article, 2020)CO2 laser annealing of SiGe core, glass-clad optical fibers is a powerful technique for the production of single-crystal cores with spatially varying Ge concentrations. Laser power, laser scan speed and cooling air flow ... -
Ge-capped SiGe core optical fibers
Wu, Wei; Balci, Mustafa H.; Muhlberger, Korbinian; Fokine, Michael; Laurell, Fredrik; Hawkins, Thomas A.; Ballato, John; Gibson, Ursula (Journal article; Peer reviewed, 2019)CO2 laser processing offers the possibility to inscribe structures within glass-clad SiGe-core fibers by altering the spatial distribution of the Si and Ge. Spatial segregation of Ge to the end of a fiber is shown via ... -
Single crystal semiconductor-core optical fiber*
Wu, Wei; Song, Seunghan; Balci, Mustafa H.; Laurell, Fredrik; Cantwell, Patrick; Ballato, John; Gibson, Ursula (Journal article; Peer reviewed, 2019)Semiconductor-core fibers are improved by removal of grain boundaries. We use a CO2 laser to process silicon-based cores; an alloying element reduces both the temperature and speed required for formation of a single crystal.
