Low-Crosstalk and Low-Loss Multi-Core Fiber Utilizing Fiber Bend
Fiber design and fabrication Fiber optics optical communications
2015/5/26
We designed and fabricated a multi-core fiber whose attenuation is less than 0.18 dB/km and effective area is about 80 m 2 . Crosstalk was observed be less than -55.5 dB after 17.6 km propagat...

We design a cost efficient routing algorithm and prototype a network planning tool to cost-effectively provision high-speed connections over a large carrier’s heterogeneous core DWDM network with mult...
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
2015/8/11
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...
