    "abstract": "Switching anisotropic molecules from strongly-absorbing to\nstrongly-amplifying through a transparent state is shown to be possible by\napplication of dc or ac control electric fields without the requirement of the\npopulation inversion. It is based on decoupling of the lower-level molecules\nfrom the resonant light while the excited ones remain emitting due to their\nstate-dependent alignment. The amplification index may become dependent only on\na number of excited molecules and not on the population of the lower state. A\nsuitable class of molecules and applications in optoelectronics, fiberoptics\nand nanophotonics are outlined.",
