The use of long-period gratings (LPGs) to distribute optical power from one core to all the cores in a multicore fiber (MCF) is theoretically analyzed. Simple analytical expressions that describe the mode power's evolution along the LPGs are derived from the coupled mode equations. This study demonstrated the power transfer between cores in a MCF promoted… (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.
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)
We propose a technique to inscribe long period gratings (LPGs) in standard single-mode fibers (SSMFs). The proposed method uses a commercial CO<sub>2</sub> splicer that allows for the rotation of the fiber during laser irradiation, enabling a uniform exposure around the fiber. LPGs inscribed in SSMFs with different periods are presented. Gratings can be… (More)
We describe the design and performances of a strictly non-blocking optical cross-connect node for WDM wavelength path networks, tested with 2 x 2 x 2.488 Gb/s, externally modulated and 200 GHz spaced WDM signals.
