Extruded singlemode, high-nonlinearity, tellurite glass holey fibre

Extrusion of complex preforms for microstructured optical fibers

“…One distinct advantage of extrusion is that non-circular holes can be produced, which has been demonstrated to date for relatively simple preforms with 3 non-circular holes [5][6][7][8][9]. With our new die design concept, large numbers of non-circular holes can be readily produced by using blocking elements of appropriate shape.…”

“…A promising alternative technique is billet extrusion, which has been shown to be a versatile, reproducible single-step approach to fabrication of soft glass and polymer preforms with up to 12 holes [5][6][7][8][9]. However, to produce even these relatively simple structures, extrusion dies with relatively complex internal structures were used.…”

Mid-IR Supercontinuum Generation From Nonsilica Microstructured Optical Fibers

“…This technique has now been used to produce a broad range of fiber geometries in a number of compound glass materials including lead silicate [35], bismuth oxide [29], and tellurite [36] glass materials. The geometry that has been used for many of these demonstrations is the so-called "wagon-wheel" (WW) fiber, which is a micrometer-scale solid core suspended by three long fine glass struts that optically isolate the core within a robust solid jacket.…”

Efficient near-infrared supercontinuum generation in tellurite holey fiber pumped 320nm within the normal dispersion regime

“…The glass composition is 75TeO 2 -20ZnO-5Na 2 O (mol. %) (TZN), and the fiber preform was made using an in-house extrusion technique [3]. Fig.…”
