Abstract: GeSn compounds have made many interesting contributions in photodetectors (PDs) over the last ten years, as they have a detection limit in the NIR and mid-IR region. Sn incorporation in Ge alters the cut off… read more here.

DOI: 10.1088/1681-7575/aa5b65
Abstract: We demonstrate that the individual single pulse of a nano-second laser can be used to measure the spectral responsivity of photovoltaic detectors. With this new scheme, the relative spectral responsivity of a photodiode can be… read more here.

DOI: 10.1088/1681-7575/ab3fd1
Abstract: Hyperspectral cameras capture the spectral power distribution of the objects in the imaged view via dozens of narrow-band spectral channels of the camera. Knowledge of the spectral responsivity of the channels is essential when interpreting… read more here.
