Splicing Ge-doped photonic crystal fibers using commercial fusion splicer with default discharge parameters

Abstract

A novel technique for splicing a small core Ge-doped photonic crystal fiber (PCF) was demonstrated using a commercial fusion splicer with default discharge parameters for the splicing of two standard single mode fibers (SMFs). Additional discharge parameter adjustments are not required to splice the PCF to several different SMFs. A low splice loss of 1.0 approximately 1.4 dB is achieved. Low or no light reflection is expected at the splice joint due to the complete fusion of the two fiber ends. The splice joint has a high bending strength and does not break when the bending radius is decreased to 4 mm.

Improved bending property of half-filled photonic crystal fiber

“…Secondly, as shown in Figs. 1(a2) and 1(e), one end of the PCF with the groove was fused into a spherical end at a distance of 5 mm from the groove to completely collapse the air holes at the fiber end by an arc discharge technique [23] or a CO 2 laser irradiation technique [24]. Another end of the PCF was spliced to a standard singlemode fiber (SMF) by an arc fusion splicing technique [23,25].…”

Fusion splicing soft-glass suspended core fibers to solid silica fibers for optical fiber sensing

“…Several low-loss and robust splice connections between silica-based MOFs and conventional solid silica fibers have been demonstrated in the past using a variety of fusion splicing techniques [12][13][14], with the most prominent being electric arc fusion splicing [15,16] due to its low cost and wide availability. However, splicing soft-glass MOFs to conventional solid silica fibers involves additional challenges such as their extremely different glass softening temperatures, different thermal conductivities and heat capacities [17,18].…”

Temperature-controlled transformation in fiber types of fluid-filled photonic crystal fibers and applications

“…1(a). One end of the PCF with a length of 500 mm was spliced to a standard single-mode fiber (SMF) with a splice loss of about 1.5 dB using the arc fusion-splicing technique [7]. Another end of the PCF was cleaved and then immersed into a refractive-index-matching liquid with a thermo-optic coefficient of −4.15ϫ 10 −4 /°C from Cargille Labs (n = 1.550 at room temperature, http:// www.cargille.com).…”
