Progress in the Fabrication of the Next-Generation Soft Glass Microstructured Optical Fibers

Computational Modeling of Hole Distortion in Extruded Microstructured Optical Fiber Glass Preforms

“…Contrary to other approaches such as stacking [3,4], drilling [5][6][7] and casting [8,9] which have limitations in terms of geometry [10] and surface quality [11][12][13], billet extrusion appears to provide a nearly unlimited range of possibilities in terms of the geometric arrangement of holes that can be achieved within a cross-section [1,2]. To reach its full potential, however, for some preform shapes [1,14] it is necessary to account for distortion and drift of the holes in the preform, i.e., the difference between the pattern of the die exit and that of the final preform, in order to optimize die design to achieve a targeted geometry.…”

“…The billet extrusion process for the manufacture of preforms used to draw microstructured optical fibers (MOFs) has been shown to be a robust and versatile approach that works for a wide range of glass types [1,2]. Contrary to other approaches such as stacking [3,4], drilling [5][6][7] and casting [8,9] which have limitations in terms of geometry [10] and surface quality [11][12][13], billet extrusion appears to provide a nearly unlimited range of possibilities in terms of the geometric arrangement of holes that can be achieved within a cross-section [1,2].…”

Low loss, low dispersion and highly birefringent terahertz porous fibers

“…These high birefringence porous structures have lower single mode operating bandwidth relative to porous fibers with circular shaped air-holes because there is a considerable amount of material between the air-holes and the edge of the core. Recently it has been shown that it is possible to fabricate non-circular air-holes in microstructure optical fibers made up of polymer and soft glasses through extrusion technique [13,14], indicating that the fabrication of the proposed structures are feasible.…”

New frontiers in nano-scale highly nonlinear photonic circuits for System on System (SoS) Integration

“…We commenced with F2 lead silicate glass (Schott Glass Co.), which has a refractive index of n=1.62 at 1550 nm and has been proven to be a very suitable glass for the fabrication of a range of extruded MOFs [14]. The fibers were made using a three step process (Fig.…”
