Reduction of Crosstalk by Trench-Assisted Multi-Core Fiber
Fiber characterization Fiber design fabrication
2015/5/26
Trench-assisted multi-core fiber (TA-MCF) is proposed to achieve high dense MCF design with a solid structure. The crosstalk value at 1.55 μm of fabricated TA-MCF is estimated to be –35 dB at 100 km.
Time variation of refractive index in the core of active fiber under pulsed optical pumping
Time variation refractive index active fiber pulsed optical pumping
2015/8/4
The kinetics of refractive index change in active fiber under pulsed cladding-coupled optical pumping was investigated using interferometric technique. Relaxation processes after lasing threshold was ...
A polarization maintaining air-core polymer fiber for terahertz guiding is proposed. The bandgap repels modal power from the absorbent background polymers, resulting in significant suppression of moda...
