“…However there are some affirmative reports (based on Raman and NMR investigations) on sulfophosphate glasses suggesting that SO 4 2− species do not contribute to network formation and instead these groups participate in the depolymerization of the phosphate network similar to Ti 3+ and Na + ions [34].…”

“…[ 13 , 14 ] As recently shown in fused silica PCF, these channels can be pressure-fi lled from the melt with many materials such as metals, semiconductors and low-melting-point glasses. [15][16][17][18][19][20][21] The fi rst step towards achieving a relatively large Verdet constant in a fi ber was recently taken by drawing a step-index fi ber from a heavily terbium-doped silica preform. [22][23][24] Such fi berdrawing processes, however, are limited to very specifi c combinations of core and cladding materials because their rheological and thermomechanical properties must be compatible.…”

Complex Faraday Rotation in Microstructured Magneto‐optical Fiber Waveguides

Magneto-optical glasses are of considerable current interest, primarily for applications in fiber circuitry, optical isolation, all-optical diodes, optical switching and modulation. While the benchmark materials are still crystalline, glasses offer a variety of unique advantages, such as very high rare-earth and heavy-metal solubility and, in principle, the possibility of being produced in fiber form. In comparison to conventional fiber-drawing processes, pressure-assisted melt-filling of microcapillaries or photonic crystal fibers with magneto-optical glasses offers an alternative route to creating complex waveguide architectures from unusual combinations of glasses. For instance, strongly diamagnetic tellurite or chalcogenide glasses with high refractive index can be combined with silica in an all-solid, microstructured waveguide. This promises the implementation of as-yet-unsuitable but strongly active glass candidates as fiber waveguides, for example in photonic crystal fibers.

“…Based on the EDX mapping and the PP-TOFMS findings, the process can be assumed to be controlled by both highly energetic ions in the laser plasma and the high process temperature, 973K (below the glass transition temperature of silica), that initiates an interfacial reaction between the ablated target glass material and the silica substrate. Above 873 K, the alkali metals in the compound (Te and Na) attack the silica substrate, enabling the regular dissolution of silica throughout the process and results in the formation of a welldefined metastable homogeneous modified RETS layer [23,24]. A similar phenomenon is also observed for the subsequent ablated target material, in which significant intermixing between the second layer (Yb 3+ -doped) and the first layer (Er 3+ -doped) arises.…”
