Thermal camouflage technologies, which aim at blending the infrared (IR) signature of
targets into the background to counter the IR detection, have witnessed increasing …

Nanostructured surfaces with designed optical functionalities, such as metasurfaces, allow
efficient harvesting of light at the nanoscale, enhancing light–matter interactions for a wide …

Sensors are perhaps the most important and integral components of our modern society.
With global warming and environmental pollution garnering ever-increasing attention, as …

Whispering gallery mode (WGM) optical microresonators have attracted intense interests in
the past decades. The combination of high quality factors (Q) and small mode volumes of …

Advanced materials and processing techniques are based largely on the generation and

In the short space of 15years since their first demonstration, quantum cascade lasers have
become the most useful sources of tunable mid-infrared laser radiation. This Letter …

The vast majority of gaseous chemical substances exhibit fundamental vibrational
absorption bands in the mid-infrared spectral region (≈ 2–25 µm), and the absorption of …

Silicon germanium (SiGe) has moved from being a research material to accounting for a
small but significant percentage of manufactured semiconductor devices. This percentage is …

PbSe nanocrystal colloids exhibit a well-defined excitonic structure with the lowest energy
exciton tuning from 0.5 to 1 eV, as a function of size. Band-edge fluorescence is observed …

Semiconductor nanowires have demonstrated exciting properties for nanophotonics,
sensors, energy technologies, and end-of-roadmap and beyond-roadmap electronic …
