Phys. Rev. Lett. 75, 1403–1406 (1995)Dark States in Coherent Semiconductor SpectroscopyReceived 4 April 1995; published in the issue dated 14 August 1995 The possibility of creating dark states (a concept well known in atomic systems) in semiconductors is discussed. Based on the semiconductor Bloch equations, the analysis shows that, in spite of complications due to band-structure and strong excitonic many-body effects, signatures of dark states should be observable in femtosecond nonlinear optical excitation experiments. © 1995 The American Physical Society URL:
