Superconducting Terahertz Sources with 12% Power Efficiency

چکیده
Low power efficiency is one of the main problems THz sources, colloquially known as gap. In this work we present prototypes devices based on whisker-crystals a hightemperature superconductor Bi2Sr2CaCu2O8+d with record high radiation 12% at frequency 4 THz. We employ various on- and off-chip detection techniques and, in particular, use radiative cooling phenomenon for accurate evaluation emission power. argue that such can be used creation tunable, monochromatic, continuous-wave, compact power-efficient sources.

Terahertz 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...
متن کاملBright terahertz sources
■ ■ What was terahertz science like in the early days? When I first became involved in terahertz (THz) research in the late 1980s at Columbia University, only three groups in the USA were actively investigating THz pulses produced from ultrashort laser pulses: the group at IBM led by Daniel Grischkowsky, that at Bell Laboratories led by Martin Nuss and that at Columbia University led by David A...
متن کاملTerahertz-wave Parametric Sources
Terahertz waves are the electromagnetic radiation whose frequency ranges from millimeter waves to the far infrared, shown in Figure 1. While both sides of this range have had a long history of research and development, leading to already commercially available sources, detectors, meters, and many additional devices, the terahertz wave range is still in its infancy, representing the last unexplo...
متن کاملGraphene microbolometers with superconducting contacts for terahertz photon detection
We report on noise and thermal conductance measurements taken in order to determine an upper bound on the performance of graphene as a terahertz photon detector. The main mechanism for sensitive terahertz detection in graphene is bolometric heating of the electron system. To study the properties of a device using this mechanism to detect terahertz photons, we perform Johnson noise thermometry m...
متن کاملApplications using high-Tc superconducting terahertz emitters
Using recently-developed THz emitters constructed from single crystals of the high-Tc superconductor Bi2Sr2CaCu2O8+δ, we performed three prototype tests of the devices to demonstrate their unique characteristic properties for various practical applications. The first is a compact and simple transmission type of THz imaging system using a Stirling cryocooler. The second is a high-resolution Mich...
