Abstract

Goos–Hänchen (GH) shifts in the reflected and transmitted light are investigated for $p$-polarized partially coherent light beams incident on a cavity having a quantum dot (QD) system as the intracavity medium. The coherent coupling between the two quantum dots via a tunneling field leads to tunneling-induced transparency and giant Kerr nonlinearity with vanishing absorption. The Kerr nonlinearity of the double QD system thus increases the amplitude of GH shifts in the reflected and transmitted light. The influence of the spatial coherence and the beam width of the partially coherent light fields on GH shifts in the reflected and transmitted light are also investigated, and large GH shifts are reported for the small range of the spatial coherence and the beam width of the partially coherent light field.
