2015/5/26
The fabrication of few-mode Cr-doped double-clad crystalline fiber (FMCDCF) using a multiple core tuning process is demonstrated for the first time. The FMCDCF exhibited a core diameter of 2 ± 0.6 μm ...
Polarization Insensitive Cross-Phase Modulation in 10.5-m Highly Ge-Doped Nonlinear Fiber
