First chip-scale broadband optical system that can sense molecules in mid-infrared range

Researchers have demonstrated, for the first time, a chip-based dual-comb spectrometer in the mid-infrared range, that requires no moving parts and can acquire spectra in less than 2 microseconds. The system, which consists of two mutually coherent, low-noise, microresonator-based frequency combs spanning 2600 nm to 4100 nm, could lead to the development of a spectroscopy lab-on-a-chip for real-time sensing on the nanosecond time scale.

Functional films made of environmentally friendly clay minerals and dyes

Researchers have created a transparent hybrid film that combines natural clay minerals and dyes into a material that changes color in response to environmental humidity. The color change does not involve breaking chemical bonds; the team uncovered a novel mechanism that makes the process easily reversible, for long-lasting functionality using environmentally friendly materials. Applications include environmental sensors, and state-of-the-art light amplification in displays.
