Abstract:
We propose a new fiber device, involving a nonlinear twin-core fiber in a fiber-loop reflector configuration, achieving several all-optical operations. By varying the disperson parameter β2, we generate quasi-square pulses in the positive dispersion regime and produce compressed and pedestal-free pulses (in one pass) in the anomalous dispersion regime. The stability of these phenomena under a change of β2 is also studied. A scale invariance is derived that permits operation of the device at any desired value of β2 simply by changing its length.

In the context of fiber optic communications, this "resistance" represents the losses due to the fiber-photodiode coupling.

We present material property expectation values computed directly from the fiber orientation distribution function, thereby alleviating the closure problem inherent to orientation tensors.

Abstract Inertial effects in the mechanism of fiber pullout during dynamic propagation of a bridged crack are critically examined. By reposing simple shear lag models of pullout as problems of dynamic wave propagation, the effect of frictional coupling between the fiber and the matrix is accounted for in a fairly straightforward way. The frictional sliding between the fiber and the matrix is described by a constant interfacial friction stress, the sign of which depends on the relative particle velocity of the fiber and the matrix.

Incorrect event locations are often the result of an inaccurate knowledge of the velocity model.
