含增益缺陷层的1维三元光子晶体特性研究
Study on characteristics of 1-D ternary photonic crystal containing gain medium defect layer
摘要
Abstract
In order to design a crystal with special optical characteristics, the characteristics of 1 -D ternary photonic crystal containing gain medium defects layer was studied with transfer matrix method without considering dispersion relation, and its band structure and optical amplification characteristics were analyzed and discussed. There is strong optical amplification in the passband edge 0.242μm. The thickness and optical constants of the gain medium at 0. 242μm was studied, and the characteristics of the optical amplification were discussed when changing the central wavelength of light. The results indicate that there is corresponding forbidden band on the both sides of center wavelength when the center wavelength is 0. 3μm. The influence of the band gap structures is small when changing the thickness and optical constants of the defect layer, and there is strong optical amplificatiom in passband edge 0. 242μm. This simulated data provides a theoretical guidance for photonic crystal of the desired characteristics.关键词
