We demonstrate 1.01-Pb/s transmission over 52 km with the highest aggregate spectral efficiency of 91.4 b/s/Hz by using low-crosstalk one-ring-structured 12-core fiber. Our multi-core fiber and… (More)
Trench-assisted multi-core fiber (TA-MCF) is proposed to achieve high dense MCF design with a solid structure. The crosstalk value at 1.55 µm of fabricated TA-MCF is estimated to be −35 dB at 100 km.
The cladding-thickness of trench-assisted multi-core fibres was investigated in terms of excess losses. The MCF with an effective area of 110 μm<sup>2</sup> at 1.55 μm and 181-μm cladding diameter… (More)
The various types of MCFs with very low crosstalk, large Aeff and low micro-bending loss were discussed. A 10-core MCF with two-pitch layout and a moderate cladding diameter was proposed.
Hollow-core photonic bandgap fibers exhibiting negative dispersion slope over a wide wavelength range around one micron for the fundamental air-core mode are presented by the introduction of partial… (More)
A commercially available 0.1 M solution of HClO(4) in dioxane has been shown to catalyze the glycosidation of glycosyl diphenyl phosphates. The per-O-benzyl-protected glucosyl and galactosyl donors… (More)
The Raman gain efficiency and chromatic-dispersion of a hole-assisted fiber with and without minimum allowable bending radius are measured. Numerical predictions from the theory are shown to be in… (More)
