摘要：
It is shown that in semiconductor superlattices (SL), guided electromagnetic waves traveling in the direction perpendicular to the optical axis of the SL can be generated. The regime with vertical constant electric field in a short plate of SL is considered. The effective homogeneous anisotropic medium method is used to obtain the effective differential conductivity tensor. The guided wave structure as well as the instability and amplification conditions are investigated. Discrete sets of values for the frequency of the excited guided waves and for the directions of the emitted waves are determined.
