【摘要】：基于取样光纤光栅和传输矩阵理论研制了新型光子晶体,采用两种不同介电常数的材料交替排列的周期性结构,根据取样光纤光栅传输理论得到了设计结构的反射系数和透射系数。模拟分析和测试实验表明:所设计的光子晶体结构出现了多个反射峰,光栅长度增大时会导致反射率明显增大,反射峰数目增加,但反射峰的间隔不会发生变化;调制深度增加时,带宽会明显增大;随着折射率调制量的增大,反射峰数目会增加,反射率也显著增大(增大10%左右)。
[Abstract]:Based on sampled fiber grating and transfer matrix theory, a novel photonic crystal is developed. Two kinds of materials with different dielectric constants are alternately arranged periodically. According to the transmission theory of sampled fiber grating, the reflection coefficient and transmission coefficient of the designed structure are obtained. The simulation analysis and test results show that there are several reflection peaks in the photonic crystal structure designed. When the grating length increases, the reflectivity will increase obviously and the number of reflection peaks will increase, but the interval between the reflection peaks will not change. With the increase of modulation depth, the bandwidth will increase obviously, and with the increase of refractive index modulation, the number of reflection peaks will increase and the reflectivity will increase significantly (about 10% increase).
