Strong fiber Bragg gratings in Bi-Al co-doped H 2 -loaded optical fibers using CW-Ar + laser
Fiber Bragg gratings photosensitivity Lasers fiber
2011/5/22
Bragg gratings with reflectivity >93% were fabricated in Bi-Al co-doped H 2 -loaded optical fibers. Average index changes as high as +2.5×10 -3 were obtained. Positive core stress changes indicate a c...
Tolerance to nonlinearity of 40 Gb/s BPSK-based coherent solution over legacy systems based on non-zero dispersion- shifted fibers
coherent communication optical communication
2011/5/22
We experimentally assess the performance of coherent PDM-BPSK at 40Gb/s over non-zero dispersion-shifted fiber. The BPSK-based solution is found about 7.5dB more robust than the QPSK-based solution ag...
Evaluation of the Fuse Effect Propagation in Networks Infrastructures with Different Types of Fibers
Optical communications All-optical networks Fiber optics links subsystems Fiber measurements
2010/6/4
The evaluation of the fuse effect propagation in fiber networks is analyzed. We show a relation between the void interval, the power density and the fused effect velocity for different types of optica...
Low Bending Sensitivity of Regular OM3/OM4 Fibers in 10GbE Applications
Fiber optics links subsystems Optical communications
2010/6/4
Regular graded-index multi-mode fibers exhibit low bend losses under 10GBASE-S sources launches. Improved process control of the inner part of the graded-core of OM3/OM4 fibers saves margins in 10GbE ...
Bend-Insensitive and Effectively Single-Moded All-Solid Photonic Bandgap Fibers with Heterostructured Cladding
Bend-Insensitive Effectively Single-Moded All-Solid Photonic Bandgap Fibers Heterostructured Cladding
2009/7/14
We propose a novel concept of cladding structure in all-solid photonic bandgap fibers. It promises low bending and confinement losses with single-mode operation. The mechanism is based on the new conc...
Simulations of the effect of the core ring on surface and air-core modes in photonic bandgap fibers
Fiber design and fabrication Fiber optics optical communications
2004/8/11
We show through computer simulations that the thin silica ring that surrounds the air core of a photonic-bandgap fiber introduces surface modes. The intensity profile and dispersion of these modes ind...
