Amplification research of nano inner cladding fiber based on quantum size effect

本文利用改进的化学汽相沉积法制作出纳米级InP薄膜内包层光纤；根据氢原子本征能量模型计算了InP微粒产生量子尺寸效应的相对粒径aB=8．313mm，且由量子尺寸效应计算了不同尺寸粒子的带隙能量以及相对应的光吸收波长；结果表明：当内包层薄膜材料厚度达5～50mm量级时，其能级将发生红移，产生放大性能．

This article used improved chemistry vapour deposition and drawn out the fibres with InP nano thin films. Based on the hydrogen atomic model, we calculate the, comparative size of the InP particle aB = 8. 313 nm. By the quantum size effect, we calculate the change of the energy band of particles with different sizes and light absorption wavelength. The results showed that the energy level of inner cladding materials creates a red shift, when the thickness of thin-film is 5-50 nm. The fibre creates optical amplification.
