Abstract

We demonstrate a superconductor array of subwavelength holes and split ring resonators with active thermal control over their resonant transmission. The arrays were lithographically fabricated on high temperature YBCO superconductor and characterized by terahertz-time domain spectroscopy. We observe a clear switching effect in the plasmonic as well as metamaterial devices as the superconducting film undergoes phase change at the transition temperature.
