“…The experiments were performed using THz-TDS in transmission with a bandwidth covering approximately 0.2-2.5 THz. The details of the experimental setup are discussed in a previous paper [8]. The Tl 2 Ba 2 CaCu 2 O 8 film (700 nm) was grown on a 10mm×10mm MgO substrate in a two-step process.…”

We have unambiguously observed the c-axis Josephson Plasma Resonance (JPR) in high-T c cuprate Tl 2 Ba 2 CaCu 2 O 8 superconducting thin films employing terahertz time-domain spectroscopy in transmission as a function of temperature in zero magnetic field. These are the first measurements of the JPR temperature dependence of a high-T c material in transmission. With increasing temperature, the JPR shifts from 705 GHz at 10 K to ∼170 GHz at 98 K corresponding to a c-axis penetration depth increasing from 20.1±0.6 µm to 84±9 µm. The linewidth of the JPR peak increases with temperature, indicative of an increase in the quasiparticle scattering rate. We have probed the onset of the c-axis phase coherence to ∼0.95T c . The JPR vanishes above T c as expected.

“…The sample and reference were mounted on the holder such that the THz pulses were at normal incidence to the substrate with the E-field normal to the gaps of the DSRR. Photoexcitation of silicon was achieved using optical-pump THz-probe (OPTP) spectroscopy [10]. The OPTP system provided amplified, ~ 50 fs, near infrared laser pulses with a center wavelength of 800 nm and a repetition rate of 1 kHz pumping on the sample to optically excite free charge carriers in the silicon.…”

In this paper, we present our recent progress on three-dimensional (3D) metamaterials at terahertz (THz) frequencies.Using a "bottom-up" multilayer electroplating technique, a flexible and a broadband tunable metamaterial was fabricated and characterized. In agreement well with numerical simulations, characterization on these 3D metamaterials by THz time domain spectroscopy (THz-TDS) indicates excellent performance of 3D metamaterials in manipulating electromagnetic waves. The successful fabrication of these 3D structures from well-defined building blocks provides a new pathway towards "bottom-up" 3D metamaterials for potential applications at THz frequencies.
