Hot-electron bolometric mixer with negative differential resistance
Chang Yoo, Akim A. Babenko, Boris S. Karasik
We demonstrate that the conversion gain of a superconducting hot-electron bolometer (HEB) mixer can be increased by biasing the device within the negative differential resistance (…

THz Metal-Mesh Bandpass Filters with Diamond-shaped Apertures for Sensitive THz Receivers
Changyun Yoo, Jeffrey L. Hesler, Boris S. Karasik
We present high-performance terahertz (THz) metal-mesh bandpass filters developed to mitigate direct detection effects in sensitive THz receivers based on superconducting hot-elect…
