Splice-loss in liquid-filled photonic crystal fibers

In this paper, we have estimated splice-loss due to splicing of liquid-filled photonic crystal fiber (LFPCF) with single mode step index fiber using our full-vectorial finite difference method at wavelength 1.55 μm with change in various fiber parameters. We tailored the LFPCF parameters to achieve the minimum splice loss and found very minimum loss at the pitch size ranging from 2.0 μm to 4.0 μm at the relative air hole size (d/Ʌ) 0.45. Further, we have elucidated the splice loss due to the transverse offset. In this analysis, it is seen that the loss is increasing gradually when the transverse offset value increases. In our investigation, we considered the LFPCF having the first ring filled with liquid of 20% water-glycerin solution. Our computation technique to calculate various propagation characteristics including splice loss of LFPCF with or without any transverse offset will have significant contribution to the system designers.
