HIGHLIGHTS
- who: F. T. Armand Pilon from the Laboratory, Villigen, Switzerland have published the research: Investigation of lasing in highly strained germanium at the crossover to direct band gap, in the Journal: (JOURNAL) of 18/07/2022
- what: The authors demonstrate using Ge microbridges with strain up to 6.6% a powerful method for determining the population inversion gain and the material and optical losses of group IV lasers. The authors show that by choosing appropriate values for the carrier temperature and line broadening, as well as the cavity losses, the TB-model accurately predicts lasing . . .
