Data for CO2 laser-induced directional recrystallization to produce single crystal silicon-core optical fibers with low loss

Data for the research paper Healy, Noel, Fokine, Michael, Franz, Yohann, Hawkins, Thomas, Jones, Maxwell, Ballato, John, Peacock, Anna C. and Gibson, Ursula J. (2016) CO2 laser-induced directional recrystallization to produce single crystal silicon-core optical fibers with low loss. Advanced Optical Materials, 1-4. (doi:10.1002/adom.201500784). The paper examines reduced losses in silicon-core fibers are obtained using CO2 laser directional recrystallization of the core. Single crystals with aspect ratios up to 1500:1 are reported, limited by the scan range of the equipment. This processing technique holds promise for bringing crystalline silicon-core fibers to a central role in nonlinear optics and signal processing applications.
