Terahertz saturable absorption in superconducting metamaterials

We present a superconducting metamaterial saturable absorber at terahertz frequencies. The metamaterial was designed to have a resonant absorption peak at 0.5 THz for T= 10K. The absorber consists of an array of split ring resonators (SRRs) etched from a 100 nm YBa sub(2) Cu sub(3) O sub(7) film. A...
