Photon Drag in Quantum Wells Embedded in a Planar Microcavity

Abstract

A theoretical analysis of the photon drag arising from intersubband transitions in quantum wells embedded in a planar microcavity has been performed. Deriving from the density-matrix approach, the photon-drag response function and the expression for the integrated photon-drag current have been given. On the basis of the Maxwell-Lorentz equations, the expression of the field in each layer is obtained. Then, by matching the boundary conditions, the field in the quantumwell microcavity structure is rigorously determined, the determined field is then 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 wells and the microcavity.

Detuning Photon Drag in Quantum Wells Embedded in an Asymmetric Fabry-Perot Microcavity by Means of Electric Field

“…Using a local field theory the asymmetry of the spectrum has been predicted [16] and confirmed experimentally [17,18]. More recently, photon drag in microcavity has been studied and the influences of the microcavity on photon drag have been shown [19]. The electric field effects on linear and nonlinear optical responses have been extensively studied in usual quantum well structures, applications based on such effects have been proposed [20].…”
