Dispersion Effects of Fiber Bending Performed on Microstructured Fiber

“…In general, bent fiber can theoretically guide two coupling super-modes: the fundamental mode exhibiting negative chromatic dispersion and the cladding mode (practically, it is often a gallery of cladding modes) characterized by positive value of dispersion coefficient. The minimum dispersion is determined at the wavelength, for which the difference of the two values of effective index corresponding to the two super-modes is zero, which occurs at the phase-matching wavelength (1), as predicted by Auguste et al [21]:…”

Study on dual-concentric-core dispersion compensation photonic crystal fiber

“…To obtain a very high dispersion, lots of designs have been proposed, such as W-model, multi-cladding model, dualconcentric-core model [2][3][4][5][6][7][8][9][10][11][12] and so on. However, the dualconcentric-core model does better than the others.…”

“…The first conventional DCCF with D of -100 ps/km/nm around1.55 µm was proposed in document [2]. In [3][4][5][6], D were attained -900 ps/km/nm, -1800 ps/km/nm, -5100 ps/km/nm respectively at 1.55 µm by optimizing structural parameters. In recent years, along with the emergence of PCF, a novel type of DCCF based on PCF is appeared.…”

“…So the fundamental mode is selected because it yields a large negative chromatic dispersion. However, in practice, when light is launched into the fiber, the high modes including second mode suffer a high transmission loss with propagation and virtually becomes extinct within a short length of the DCCPCF [3].…”

“…Recently, because the structure design of the photonic crystal fiber (PCF) is flexible and dual-concentric-core fiber (DCCF) could attain high negative dispersion easily, some investigations of dual-concentric-core photonic crystal fiber (DCCPCF) [2][3][4][5][6][7][8][9][10][11][12] have attracted considerable attentions.…”
