Abstract
The burning-hole behavior of intersubband absorption in semiconductor superlattices is studied by means of the two- subband model. The Maxwell-Bloch equations of laser- superlattice interaction are derived and solved at the steady condition. The absorptive coefficient as a function of the frequency of probe laser is given. The theoretical and numerical results how that the burning hole of the absorption-frequency curve occurs when the pump laser is enough strong. The burning-hole behavior is related closely to the structure of the semiconductor superlattices.
