Laser post-processing of GaAs core fibers: A first step towards in-fiber longitudinal, lateral, and radial junctions
Source abstract
Abstract
The Companion Paper [Zaengle T, Gibson UJ, Hawkins TW, McMillen C, Ballato J. Comprehensive phase analysis of GaAs:(Cu, Au) systems in molten core fibers. Opt Mater (Amst). 2024;150(March):115256. doi:10.1016/j.optmat.2024.115256] presents the thermochemical analysis of the GaAs:Cu and GaAs:Au phases in flux-assisted molten core fiber. In this work, fibers of these systems are post-processed using a CO2 laser to segregate the flux and recrystallize the GaAs. The volatility and incongruency of the GaAs are shown to make in-fiber single crystal growth complex, with thermal and structural limitations of the borosilicate glass cladding also influencing the process. Despite these challenges, the GaAs:flux fibers were successfully segregated in the lateral, longitudinal, and radial directions, demonstrating the first steps towards in-fiber devices with GaAs.
