| Abstract Scope |
An extension of the molten core method (MCM) is reported that successfully yielded optical fibers containing GaAs and ZnSe core. Such materials exhibit volatility at or above their melting temperatures and cannot normally be drawn into fiber. With the addition of a flux phase (Sn, Cu, and Au for GaAs and Cu8GeSe6 for ZnSe) the melting temperature and the vapor pressure of the volatile phase can be reduced which then allows for the fabrication of these novel in-fiber optoelectronic species. A CO2 laser post-processing method is employed to spatially segregate the semiconductor phase from the flux within the core of the fiber. This work demonstrates the fabrication of GaAs and ZnSe fiber using conventional industry methods opening the door to novel optoelectronic and photonic devices. |
