摘要By combining nano-technology with fiber technology, an optical fiber doped with semiconductor nano-particles as InP is fabricated by using the modified chemical vapor deposition (MCVD) method. Proved by experiment, the fiber has excellent waveguide characteristics, and the concentration of InP is approximately 0.1%. By using a scanning electron microscope, a stereo-scan photograph of the fiber is obtained, and based on the graph, presentations of the fiber under both magnetic and electronic fields are simulated, the effective core area Aeff ≈ 10μm2 is calculated, and so is the nonlinear index γ =10.53W-1/Km of the fiber. This research leads a new method of high nonlinearity fiber fabrication.
