A bias-selectable near-infrared (NIR) and extended short wavelength infrared (eSWIR) dual-band bandgap engineered GaAsSb/AlGaAsSb/T2SL (InGa As/GaAsSb) infrared photodetector, vertically stacked in a monolithic grown on InP substrate, is demonstrated. GaAsSb NIR sub-detector and T2SL eSWIR sub-detector are operated under small forward and reverse bias, respectively. The GaAsSb sub-detector functions within the NIR spectrum, with a 100% cutoff wavelength of 1.

However, their full potential has yet to be realized due to a lack of complete understanding of their operation from the perspective of detection principles. Here, by investigating the photon transmission path and optoelectronic performance of the simulated devices, a detailed noise equivalent temperature difference (NETD) model of the T2SL MWIR FPAs was established.

Jinhua lean ham (LH), a dry-cured ham made from the defatted hind legs of pigs, has become increasingly popular among consumers with health concerns. However, the influence of fat removal on the quality of Jinhua ham is still not fully understood. Therefore, a label-free proteomics strategy was used to explore the protein differential profile between Jinhua fatty ham (FH) and lean ham (LH).
