Waveguide formation in niobium tellurite glasses by pico- and femtosecond laser pulses

Physical and structural properties of glasses in the TeO2–TiO2–Nb2O5 system

“…This fact has allowed the preparation of several glass families with added interest in optical and electrooptical applications and with noticeable advantages, in comparison with other conventional glasses. Kim et al 6,7 studied non-linear optical properties of several systems of binary tellurite glasses, Charton et al 8 determined the structural characteristics of glasses in the TeO 2 -WO 3 system, Tokuda et al 9 prepared waveguides into Nb 2 O 5 -TeO 2 glasses. Other authors have enlarged the field of knowledge about tellurite glasses with research concerning ternary and quaternary systems.…”

Concentration quenching in erbium-doped tellurite glasses

“…Recently, there has been a great deal of interest in Er 3+ -doped tellurite glass which was considered to be a well-known promising candidate for 1.5 mm broadband optical amplifier [1][2][3] and planar waveguide amplifier [4,5] in wavelength division multiplexing (WDM) system. Compared with the commercial erbium-doped silica fiber, the short path amplifiers based on tellurite glasses always need a higher Er concentration to obtain sufficient gains because their optical interaction path is shorter.…”

Visualization of femtosecond laser-induced stress anisotropy in amorphous and crystalline materials

“…Femtosecond laser machining has enabled the manufacture of a wide variety of integrated, threedimensional, multi-functional devices all on a single substrate [1][2][3][4][5][6][7][8][9][10][11][12]. While the benefits of this technology are many, there are still significant technological obstacles that must be overcome to reliably and predictably produce these devices.…”
