“…The hollow-core microstructured optical fibers (HC-MOFs) (Yablonovitch, 1987;Knight et al, 1996) have attracted much attention in optical applications over the past decade as they exhibit many unique optical properties such as controlled dispersion, endlessly single-mode operation, supercontinuum generation, and soliton propagation (Birks et al, 1997;Monro et al, 1999;Revathi et al, 2014;Skryabin and Wadsworth, 2010;Wadsworth et al, 2001) over a wide range of wavelengths that cannot be realized in conventional step-index fibers. The light guidance in HC-MOF fiber is based on the mechanism of photonic band gap (PBG) guidance.…”
