The amplified characteristic of InP nano inner cladding fiber

摘要

A novel InP nano inner cladding fiber is presented to fabricate high efficiency, stable and broad-band optical amplifier. Comparing to the heterostructure, the optical pump is adopted instead of electrical pump. So the carrier transport process of InP semiconductor material is investigated in the fiber structure. The rate-equations are deduced after the transport processes simplify to three-level energy band. By simulation, it is found that high gain can be achieved in short amplified fiber. It is fit for integration.
