Electromagnetic simulation of quantum well structures

Local polariton modes and resonant tunneling of electromagnetic waves through periodic Bragg multiple quantum well structures

We study analytically defect polariton states in Bragg multiple quantum well structures and defect-induced changes in transmission and reflection spectra. Defect layers can differ from the host layers in three ways: exciton-light coupling strength, exciton resonance frequency, and interwell spacing. We show that a single defect leads to two local polariton modes in the photonic band gap. These ...

Two-dimensional simulation of quantum well lasers

We describe a two-dimensional model for quantum-well lasers that solves self-consistently the electrical and optical equations. The model includes a wavelengthand position-dependent gain function which is derived from a quantum-mechanical calculation. We have also incorporated the effects of strain into the model, through an anisotropic parabolic band approximation of the band structure from a ...

Ultrashort electromagnetic pulse control of intersubband quantum well transitions

: We study the creation of high-efficiency controlled population transfer in intersubband transitions of semiconductor quantum wells. We give emphasis to the case of interaction of the semiconductor quantum well with electromagnetic pulses with a duration of few cycles and even a single cycle. We numerically solve the effective nonlinear Bloch equations for a specific double GaAs/AlGaAs quantum...
