Abstract
The characteristics of optical bistability (OB) induced by intersubban d transitions (ISBTs) in semiconductor superlattices (SLs) are studied by means of the density matrix method. It is shown that the ISBT-indu ced OB can be realized in a wide frequency range, and its hysteresis l oop is much larger than that of a two-level system. These behaviors of the ISTB-induced OB are intimately related to the electron tunneling effects in SLs. Copyright (C) 1996 Elsevier Science Ltd
