摘要
A multiwell interband cascade laser with a tunnel junction within a single waveguide and radiation emission through the substrate is implemented for the first time. It is shown that such a laser heterostructure design provides the more efficient population of quantum wells in comparison with a conventional multiwell laser with radiation emission through the substrate, due to which the lasing threshold is significantly lowered.
