Electromagnetically induced transparency of a quantum wire with longitudinal heterostructures under the influence of external electric and magnetic fields
G. Rezaei, Somayeh Mohammadi Bigdeli
In this article the electromagnetically induced transparency of a quantum wire with longitudinal heterostructures, under the influence of external electric and magnetic fields are investigated. To this end, the group velocity and absorption coefficient of the medium in the presence of external electric and magnetic fields are studied. It is found that, electromagnetically induced transparency occurs in the system and its frequency, transparency window and group velocity of the probe field strongly depend on the external electric field and the well width. In comparison with atomic system, one may control the electromagnetically induced transparency and the group velocity of light in these structures with the well width.
