摘要：
The third-order nonlinear intersubband absorption in superlattices is studied theoretically by means of a general formalism of the Kronig-Penney model given recently. It is shown that there is a general relation between the tunnel bandwidth and the minimum optical saturation intensity. The physical origin of this relation is analyzed.
