HIGHLIGHTS
- who: Jussi Rossi et al. from the Tampere University, Tampere, Finland have published the article: Optical power detector with broad spectral coverage, high detectivity, and large dynamic range, in the Journal: (JOURNAL) of 25/03/2022
- what: The authors report a generalpurpose optical power detector based on the photoacoustic effect. The authors demonstrate an exceptionally large spectral coverage from ultraviolet to far infrared, with the possibility for further extension to the terahertz region. The authors show for the first time that the same fundamental principle can lead to a simple and universal electromagnetic power detector . . .
