“…It is well known that complete exchange of power between the HE1 l mode of the rod guide and the HE1 l mode of the tube guide is possible when the two guides are phase matched [4]. Since this does not occur naturally at any wavelength (as opposed to two identical rod guides) due to their different dispersion characteristics it would be necessary to design the rod and tube guides for phase matching.…”

The main purpose of this work is to demonstrate and physically explain the operation of coaxial directional coupling.Two approaches have been used to explain the behavior of the coaxial couplers. Mode coupling theory and normal mode interference have been successfully employed in the design of such couplers.Experimental observation of switching and beatlength was in agreement with the theory. Such fibers, when designed as couplers are multimoded supporting at least three modes. However, it is possible for such fibers to be single moded.

In this article, the effect of strain on mode field diameter (MFD) and effective area (A eff ) in a modern multilayer WII type single mode optical fiber is investigated. The modal analysis of the fiber structure is based on linear polarized (LP) approximation method. The simulation results depict that both mode field diameter and effective area grow as a result of increment in tensile strain. The overall effect is observed in a slight rise in quality factor (Q f ) of the fiber. Likewise, enlargement in amplitude of compressive strain leads to decrement in MFD and A eff . However, among the optical and geometrical parameters of the fiber structure, Δ has the most considerable impact on both MFD and A eff variation whilst R 1 shows the least effect. In other words, any shift in the value allocated to Δ results in substantial change in the MFD and A eff alteration due to strain. To eliminate this effect, the higher amounts for Δ are preferable which is related to the layering structure of the WII type optical fiber.

“…Coupled mode theory is presented, for example, in [19,20]. 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.…”
