Electromagnetic emission from a superlattice during ultrafast carrier excitation under the conditions of a Wannier-Stark ladder
Molotkov S. N.
When a superlattice in a uniform electric field is excited by ultrashort pulses, the shape of the emission signal is determined primarily by the relation between the pulse length and the reciprocal step of the Wannier-Stark ladder. A frequency detuning does not play a fundamental role. © 1995 American Institute of Physics.
