Bismuth glass holey fibers with high nonlinearity

Abstract

Abstract:We report on the progress of bismuth oxide glass holey fibers for nonlinear device applications. The use of micron-scale core diameters has resulted in a very high nonlinearity of 1100 W -1 km -1 at 1550 nm. The nonlinear performance of the fibers is evaluated in terms of a newly introduced figure-of-merit for nonlinear device applications. Anomalous dispersion at 1550 nm has been predicted and experimentally confirmed by soliton self-frequency shifting. In addition, we demonstrate the fusionsplicing of a bismuth holey fiber to silica fibers, which has resulted in reduced coupling loss and robust single mode guiding at 1550 nm. 440-442 (2003)

Enhancement of the sensitivity of gas sensor based on microstructure optical fiber

“…However, this proposed structure can be fabricated by the present available technology due to technological advancement in the fabrication of PCFs. Several methods have been developed for the fabrication of microstructured fibers such as stack and draw [27], sol-gel casting [28], drilling [9], and extrusion [29] methods. Stack and draw methods are bounded to closest-packed geometries such as triangular or honeycomb lattices and cannot easily generate circular patterns.…”

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

“…This cane is inserted into an extruded jacket tube. Finally, this assembly is drawn down to the fiber [2]. The preform images were taken with a digital camera, whereas the fiber images were taken with a scanning electron microscope.…”

“…The concept of small-core high-NA fibers with a core suspended in air via 3 fine struts was developed for highnonlinearity applications using high-index glasses [1][2][3]. We extended this concept to fibers for evanescent field based sensing, which requires low-index glasses to achieve a high power fraction of light in the air holes [7].…”

“…We extended this concept to fibers for evanescent field based sensing, which requires low-index glasses to achieve a high power fraction of light in the air holes [7]. We commenced the work on low-index glass suspended-core fibers using the same die design that has been employed successfully for high-index glass fibers of the same type [2,3]. We used commercially available lead silicate glass F2, which exhibits both low index and sufficiently low softening temperature to be used for preform extrusion.…”

“…Recently, significant progress in the development of MOFs with extremely high nonlinearities using high-index soft glasses such as lead silicate, bismuth and tellurite [1][2][3] has been achieved. First high-nonlinearity fibers with dispersion control were demonstrated [3].…”
