TL;DR: Initial experimental details and properties of a silicon core, silica glass-clad optical fiber fabricated using conventional optical fiber draw methods showed the core to be highly crystalline silicon.

TL;DR: A mid infrared silicon Raman amplifier is demonstrated, for the first time, which can potentially extend silicon photonics' application beyond data communication in the near IR and into the mid-IR world of remote sensing, biochemical detection and laser medicine.

TL;DR: X-ray diffraction and spontaneous Raman scattering measurements showed the core to be very highly crystalline germanium with no observed secondary phases, which should make these fibers of significant value for fiber-based mid- to long-wave infrared and terahertz waveguides and Raman-shifted infrared light sources once high-purity, high-resistivity germanum is employed.

TL;DR: A review of recent progress in the nascent field of glass-clad semiconductor core optical fibers can be found in this article, where the fundamental performance limits are discussed as well as a range of present and future applications.

TL;DR: This work constitutes a proof-of-concept that optical fibers comprising semiconductor cores of higher crystallographic complexity than previously realized can be drawn using conventional fiber fabrication techniques, and may open the door to future fiber-based nonlinear devices.
