Abstract In this paper, a plasma photonic crystal (PPC) for infrared radiation modulation which is composed of indium tin oxide (ITO) and plasma is proposed. The performance of plasma photonic crystal in near infrared radiation modulation is researched by transfer matrix method (TMM). The simulation results show that the near infrared radiation pass band can be adjusted by the changing of plasma frequency of plasma. The reflection to near infrared radiation by plasma photonic crystal increases with plasma frequency and that of absorption decreases. In addition, the modulation performance of the plasma photonic crystal at different incidence wave angles is also studied. The results show that the incident wave angles have little effect on the transmission of plasma photonic crystal in near infrared band. The reflection of the plasma photonic crystal to near infrared radiation decreases with increasing of the incident wave angle, but that of the absorption increases with the incident wave angle. Therefore, the proposed plasma photonic crystal has a potential application in tunable near infrared filter devices.

基于等离子体光子晶体的近红外辐射调制研究

摘要 本文提出了一种由氧化铟锡(ITO)和等离子体组成的用于红外辐射调制的等离子体光子晶体(PPC)。采用转移矩阵法(TMM)研究了等离子体光子晶体在近红外辐射调制中的性能。仿真结果表明,改变等离子体的等离子体频率可以调节近红外辐射通带。等离子体光子晶体对近红外辐射的反射随着等离子体频率的增加而增加,而吸收的则减少。此外,还研究了等离子体光子晶体在不同入射波角下的调制性能。结果表明,入射波角对等离子体光子晶体在近红外波段的传输影响不大。等离子体光子晶体对近红外辐射的反射随入射波角的增大而减小,而吸收的反射随入射波角的增大而增大。因此,所提出的等离子体光子晶体在可调谐近红外滤光器装置中具有潜在的应用。
