In this roadmap article, we have focused on the most recent advances in terahertz (THz)
imaging with particular attention paid to the optimization and miniaturization of the THz …

Terahertz (THz) science and technology have greatly progressed over the past two decades
to a point where the THz region of the electromagnetic spectrum is now a mature research …

Science and technologies based on terahertz frequency electromagnetic radiation (100 GHz–
30 THz) have developed rapidly over the last 30 years. For most of the 20th Century …

Traditional terahertz (THz) equipment faces major obstacles in providing the system cost
and compactness necessary for widespread deployment of THz applications. Because of …

We present a terahertz quantum cascade laser operating on a thermoelectric cooler up to a
record-high temperature of 210.5 K. The active region design is based on only two quantum …

We review the most recent technological and application advances of quantum cascade
lasers, underlining the present milestones and future directions from the Mid-infrared to the …

Wireless data rates are expected to be around 10Gbps or even more within the upcoming
decade. The realization of such high data rates is unlikely with the currently licensed bands …

Significance: An increasing interest in the area of biological effects at exposure of tissues
and cells to the terahertz (THz) radiation is driven by a rapid progress in THz biophotonics …

In the last decade quantum cascade lasers (QCLs) have become the most widely used
source of mid-infrared radiation, finding large scale applications because of their wide …

Room temperature operation of terahertz quantum cascade lasers (THz QCLs) has been a
long-pursued goal to realize compact semiconductor THz sources. In this paper, we report …
