    Abstract: Recently great interest has been aroused by the development of photonic crystal fibers (PCFs). Hollow-core photonic crystal fibers (HC-PCFs) can guide light inside the hollow core by photonic bandgap or inhibited-coupling mechanisms. HC-PCFs exhibit low propagation losses at 1.064 μm and the 1.51-1.60 μm range. The HC-PCFs are now implemented as an... Show More

    Abstract: Rational adjusting 3 main parameters of fast p+nn+ structure such as the forward voltage drop, reverse recovery time and reverse current means to control rationally the carrier lifetime of high and low level and the space-charge generation carrier lifetime. In other words, we should make the lifetime of the high-level carrier and the space charge g... Show More

    Abstract: Rare-earth-doped optical fibers are one of the most promising solid-state lasers. In these fiber lasers, a cladding-pumping scheme using large-mode-area double-clad fibers (DCFs) is utilized to increase the overall conversion efficiency of pumping light and to overcome the restriction owing to the onset of stimulated Raman scattering. On the other ... Show More
