摘要
We propose a model, by taking advantage of quantum interference in a semiconductor quantum-well structure, for two-color lasing without population inversion. In the suggested three-well system, transitions of the lowest three excited states, being coupled to a common continuum by tunneling, to the ground state have been studied. Our results show that the emission spectrum can be arranged in accordance with the initial conditions of the excited states. With the emission peaks located in the vicinities of the absorption zeros resulting from destructive interferences, the nonreciprocal emission-absorption spectra provide a choice of inversionless lasing at two frequencies.
