We present a theoretical model to incorporate the quantum mechanism of two‐photon transitions into macroscopic operations. The two‐photon transition is described as a two‐step interband–intraband transition within the one‐band envelope‐function framework and is coupled with drift–diffusion as well as the potential distribution. In0.53Ga0.47As/InP superlattices (SLs) are chosen as the initial candidate...
