Large Area Flexible Thin Layer Terahertz Detector

open access: yesAdvanced Electronic Materials, 2023
Due to the low photon energy in the relevant frequency band, fewer materials can directly excite carriers, and an extreme lack of high‐performance, large‐area detectors, limit the promotion, and development of 6G technology.

Differential CMOS Sub-Terahertz Detector with Subthreshold Amplifier. [PDF]

open access: yesSensors (Basel), 2017
We propose a differential-type complementary metal-oxide-semiconductor (CMOS) sub-terahertz (THz) detector with a subthreshold preamplifier. The proposed detector improves the voltage responsivity and effective signal-to-noise ratio (SNR) using the ...

Large-area photonic circuits for terahertz detection and beam profiling [PDF]

open access: yesLight: Science & Applications
Deployment of terahertz communication and spectroscopy systems relies on the availability of low-noise and fast detectors, with plug-and-play capabilities. However, most current technologies are stand-alone, discrete components.

Regenerative terahertz quantum detectors [PDF]

open access: yesAPL Photonics, 2021
Because of the ultrafast and photon-driven nature of the transport in their active region, we demonstrate that quantum cascade lasers can be operated as resonantly amplified terahertz detectors with wide RF bandwidth. Tunable responsivities up to 50 V/W and noise equivalent powers down to 100 pW/Hz1/2 are demonstrated at 4.7 THz.
