In this paper, the optical power transfer promoted by long-period gratings (LPGs) inscribed in Multicore Fibers (MCFs) is studied. Simple analytical expressions that describe the mode power's evolution along the LPGs in a 1+n core fiber are derived from the coupled mode equations. The viability of using this technique to develop a device that distribute a(More)
Surface aquatic vehicles present a complex dynamic behavior since they operate between two different fluids, air and water, each one with a different density and viscosity. Wind and surface currents affect vehicle motion in different manners. This paper shows the development of an estimator based on an artificial neural network which is used for wind(More)
In this work we report the development of is a steady state Erbium doped fiber amplifier model in the form of a graphical user interface (GUI), created with Matlab®. The model and the interface were tested by accessing the influence of length, input and pump powers in the gain performance of the amplifier.
