Paper Abstract

The film thickness and the composition of the fiber can be controlled by ALD (Atomic Layer Deposition) process at atomic level. Therefore, a special fiber with the structure of alternating deposition of doped Nano-semiconductor materials (such as PbS, InP etc.) and SiO2 can be manufactured by ALD process. In a word, this would not only change the manufacturing technology of fiber, but also greatly changed the structure of fiber. In this paper the Band-gap energy and absorption wavelength is calculated for different nano-particle size by the influence of Quantum Size Effect. Considering the 1550 nm wavelength used widely in optical communication, the particle size is calculated, which is used in a simulated structure of the special fiber. Then Based on the simulation of the distribution of optical field, we draw a conclusion that the light field intensity in the special fiber is lower than the single fiber. Therefore, a high-power pumping light should be added if the special fiber is used as amplifying fiber.
