We discuss the applicability of photonic crystal fiber (PCF) with a uniform air-hole structure to high-speed and wide-band transmission over conventional telecommunication bands. We design the PCF to maximize the effective area by utilizing the macro-bending losses of the fundamental and first higher order modes (HOM) and clarify that a single-mode and low bending loss PCF can realize the largest...
We investigate the scattering loss in photonic crystal fibers with different structures by using bi-directional OTDR measurement. Their intrinsic Rayleigh scattering coefficient is slightly less than that of conventional pure silica core single-mode fiber.
Photonic crystal fiber is a promising candidate for future transmission media due to its unobtainable features in a conventional single-mode fiber. We discuss some important problems to realize a PCF for transmission purpose.
PCFs can have a higher tensile strength than conventional silica fibers because the holes prevent flaws from growing. A proper designed PCF shows a tensile strength of 7 kgf which is unobtainable with commercial SMF.
A low-loss photonic crystal fiber (PCF) is an important transmission media for future transmission systems. We describe an optical attenuation of a PCF and discuss a possibility of a low-loss PCF comparable to that of a conventional single-mode fiber
