摘要：

We demonstrate an engineered composite film that dynamically switches resonant transmission behavior of terahertz radiation from band-stop to band-pass under appropriate optical pumping. In the absence of pumping, a resonant band-stop behavior is observed arising from metallic split-ring-resonators fabricated on an epitaxial silicon film that was already patterned into a periodic hole-array. Pumping with external infrared light, the silicon film becomes quasi-metallic, damping the planar metamaterial response and enabling a band-pass surface-plasmon resonance through the now conducting hole array. By leveraging two separate types of electromagnetic behaviors simultaneously, this composite chip paves a way for developing unique hybrid planar metamaterials. (C) 2011 Optical Society of America
