Abstract
A theoretical analysis of the photon drag arising from intersubband transitions in a single quantum well embedded in a microcavity has been performed. Based on the density-matrix theory, the expression for the integrated photon drag current is explicitly given. To determine the field, starting from the Maxwell-Lorentz equations, the field in each layer consisting of the quantum-well microcavity structure is explicitly obtained. Then, by matching the boundary conditions, the field in the quantum-well microcavity structure is precisely determined and used to calculate the photon drag current. Detailed numerical calculations show that the photon drag current can be significantly modified due to the coupling between the quantum well and the microcavity.
