Paper Abstract

Recently developed glass-clad crystalline semiconductor core optical fibers potentially offer a series of advantages over present optical fiber materials including greatly enhanced Raman cross-sections and extended infrared transparency. Indeed, the low-cost high-through-put fiberization of crystalline materials could permit a step-jump in performance critical for use in high energy laser, infrared counter-measure, communication, and sensor systems. Further, the high degree of crystallinity is of considerable scientific value since optical fiber fabrication is a highly non-equilibrium process and so achieving high degrees of crystallinity is very counter-intuitive and offers new insight into crystal growth mechanisms. This talk will review progress in glass-clad fibers possessing cores of highly crystalline silicon and germanium including anomalies in Si and Ge that may benefit fiber fabrication as well as paths forward to optimization of fiber design and performance.
