Theory of transient spectroscopy of multiple quantum well structures
A theory of the transient spectroscopy of quantum well ~QW! structures under a large applied bias is presented. An analytical model of the initial part of the transient current is proposed. The time constant of the transient current depends not only on the emission rate from the QWs, as is usually assumed, but also on the subsequent carrier transport across QWs. Numerical simulation was used to...
متن کاملOptical properties of 1D photonic crystals based on multiple-quantum-well structures
A general approach to the analysis of optical properties of photonic crystals based on multiplequantum-well structures is developed. The effect of the polarization state and a non-perpendicular incidence of the electromagnetic wave is taken into account by introduction of an effective excitonic susceptibility and an effective optical width of the quantum wells. This approach is applied to consi...

متن کاملPolariton local states in periodic Bragg multiple-quantum-well structures.
We study analytically the optical properties of several types of defect in Bragg multiple-quantum-well structures. We show that a single defect leads to two local polariton modes in the photonic bandgap. These modes lead to peculiarities in reflection and transmission spectra. Detailed recommendations for experimental observation of the effects studied here are given.
متن کاملElectron–interface phonon interaction in multiple quantum well structures
Intersubband relaxation rates due to electron interactions with the interface phonons are evaluated for multiple quantum well structures designed for step quantum well lasers operating at mid-infrared to submillimetre wavelengths. The interface phonon modes and electron–phonon interaction Hamiltonians for the structures are derived using the transfer matrix method, based on the macroscopic diel...
