“…On a different front, the IR transparency of crystalline semiconductors (Section 2) have invited efforts to draw semiconductor-core, glass-cladding fibers [389][390][391] with the amorphous cladding facilitating the drawing procedure (Section 3). Several semiconductors have been drawn continuously in this fashion, ranging from elemental semiconductors such as Si [391] and Ge [79] to compounds such as InSb [16].…”

Infrared (IR) fibers offer a versatile approach to guiding and manipulating light in the IR spectrum, which is becoming increasingly more prominent in a variety of scientific disciplines and technological applications. Despite well-established efforts on the fabrication of IR fibers in past decades, a number of remarkable breakthroughs have recently rejuvenated the field-just as related areas in IR optical technology are reaching maturation. In this review, we describe both the history and recent developments in the design and fabrication of IR fibers, including IR glass and single-crystal fibers, multimaterial fibers, and fibers that exploit the transparency window of traditional crystalline semiconductors. This interdisciplinary review will be of interest to researchers in optics and photonics, materials science, and electrical engineering.

“…A rod-in-tube (RIT) method was used to assemble the Cr 4+ -doped YAG/silica preform [3]. The silica tube was tapered in one end to form a cone shape in order to hold the Cr 4+ -doped YAG crystal rod and then a Cr 4+ -doped YAG crystal rod [4] was inserted into the tube to constitute the preform.…”

The spectroscopy and microstructure of Cr-doped fibers (CDFs) fabricated by the drawing-tower technique are investigated. The spontaneous emission spectrum exhibited broadband emission of 1.2 lm to 1.55 lm. High-resolution transmission electron microscope images showed that there were nanocrystalline structures in the core, surrounded by an amorphous matrix of SiO 2 ; they also revealed that the nanoparticle density was about 3.2 9 10 3 lm À2 near the core/clad interface, and 1.5 9 10 4 lm À2 near the core center. The results indicate preliminary success in fabricating nanocrystalline CDF with low transmission loss and crystal-like active properties.

SiO_2-clad fibers with selectively volatilized soft-glass cores

Abstract: By using a thick-walled SiO(2) tube (25-mm outside diameter, 1-mm inside diameter), a soft-glass core containing Nd or Yb-Er has its alkali (and to a lesser extent its alkaline earth) components volatilized during drawing to give a good-quality laser fiber with Nd- or Yb-Er-doped cores.
