Abstract

Metamaterials have been demonstrated for different terahertz (THz) wave devices, such as bandpass filter, absorber, polarizer rotator, etc. However, since the metamaterial normally use a silicon or quartz substrate to accommodate the metallic split ring resonators (SRRs), different functional devices are usually separated and bulky for integration. In this paper, we propose to use polymer metamaterials [1] for THz wave devices for the integrated THz photonics. The polymer metamaterial includes double- or multi-layer SRRs and use thin polymer as the spacer between each layer to control the THz wave propagation. By designing the SRR structure with certain electromagnetic functions, it is available to integrate several type devices (filter, polarizer, etc.) into the one film. Meanwhile, it also benefits the nonlinear optics research by simply attaching the metamaterial film device onto the nonlinear crystal to improve the conversion efficiency with the electric field enhancement function by the SRRs [2].
