Corrugated non-stationary optical fiber

Giant colloidal diffusivity on corrugated optical vortices.

A single colloidal sphere circulating around a periodically modulated optical vortex trap can enter a dynamical state in which it intermittently alternates between freely running around the ringlike optical vortex and becoming trapped in local potential energy minima. Velocity fluctuations in this randomly switching state still are characterized by a linear Einstein-like diffusion law, but with...

Projected non-stationary simultaneous iterative methods

In this paper, we study Projected non-stationary Simultaneous It-erative Reconstruction Techniques (P-SIRT). Based on algorithmic op-erators, convergence result are adjusted with Opial’s Theorem. The advantages of P-SIRT are demonstrated on examples taken from to-mographic imaging.

Need of Knowing Fiber Non-linear Coefficient in Optical Networks

This paper describes the need of knowing fiber non-linear coefficient in global optical networks. The basic Kerr non-linearities that appear in silica-based optical fibers have been summarized, together with their implications for optical communication systems. In this paper, the non-linear coefficient has been discussed and its measurement techniques reviewed. The brief description of each met...

A Fiber Optical Sensor For Non–Contact Vibration Measurements

Vibration tests are widely employed in many industrial fields, and in particular in aerospace industry to evaluate the mechanical behavior of parts for aircrafts and satellites. Usually, these tests are carried out with shakers, while inertial accelerometers are used to measure the shaker table acceleration from which the vibration amplitude is computed. Some applications require the measuremen...
