Linewidth and tuning characteristics of terahertz quantum cascade lasers.
We have measured the spectral linewidths of three continuous-wave quantum cascade lasers operating at terahertz frequencies by heterodyning the free-running quantum cascade laser with two far-infrared gas lasers. Beat notes are detected with a GaAs diode mixer and a microwave spectrum analyzer, permitting very precise frequency measurements and giving instantaneous linewidths of less than -30 k...
متن کاملTerahertz plasmonic composites.
The dielectric response of a polymer matrix composite can be substantially modified and tuned within a broad frequency band by integrating within the material an artificial plasmon medium composed of periodically distributed, very thin, electrically conducting wires. In the microwave regime, such plasmon/polymer composites have been studied analytically, computationally, and experimentally. Thi...
متن کاملCorrigendum: Excitation of dark multipolar plasmonic resonances at terahertz frequencies
We experimentally observe the excitation of dark multipolar spoof localized surface plasmon resonances in a hybrid structure consisting of a corrugated metallic disk coupled with a C-shaped dipole resonator. The uncoupled corrugated metallic disk only supports a dipolar resonance in the transmission spectrum due to perfect symmetry of the structure. However, the dark multipolar spoof localized ...
متن کاملPlasmonic terahertz detectors for biodetection
A report is presented on the biodetection capabilities of plasmonic terahertz detectors. Large changes in the terahertz response of plasmonic detectors loaded with solutions of globulin-free bovine serum albumin, arginine and heparin were measured for concentrations that did affect the device transfer characteristics. The consistent change of the response characteristics with specimen type and ...
متن کاملTerahertz superconducting plasmonic hole array.
We demonstrate a superconductor array of subwavelength holes with active thermal control over the resonant transmission induced by surface plasmon polaritons. The array was lithographically fabricated on a high-temperature yttrium barium copper oxide superconductor and characterized by terahertz time-domain spectroscopy. We observe a clear transition from a virtual excitation of the surface pla...
