Theory of optical gain from four-wave mixing instabilities in quantum wells

Abstract

We predict that in a typical pump-probe setup four-wave mixing instabilities associated with biexcitonic correlations in a single semiconductor quantum well can yield large optical gain in the probe and background-free four-wave mixing directions.

Large optical gain from four-wave mixing instabilities in semiconductor quantum wells

Stefan Schumacher, N. H. Kwong, Rolf H. Binder

Based on a microscopic many-particle theory, we predict large optical gain in the probe and background-free four-wave mixing directions caused by excitonic instabilities in semiconductor quantum wells. For a single quantum well with radiative-decay limited dephasing in a typical pump-probe setup we discuss the microscopic driving mechanisms and polarization and frequency dependence of these instabilities.

Exciton-scattering and biexciton contributions to four-wave mixing signals in semiconductor quantum wells

N. H. Kwong, T. Takayama, I. Rumyantsev +1 more

Summary form only given. Four-wave mixing processes in semiconductor quantum wells have been studied intensively for many years, because they allow for a detailed investigation of ultrafast many-body processes such as quantum correlations and quantum coherences. From a theoretical point of view one can roughly divide the existing approaches into two categories: (i) fully microscopic theories based on the bandstructure and on Coulomb interactions between electrons and holes, and (ii) phenomenological few-level models.

Four-wave Mixing Oscillators

G. Grynberg

A non-linear medium interacting with two intense counterpropagating beams can give rise to a four-wave mixing gain for a probe wave [1]. This gain can be sufficient to observe oscillation when the medium is placed inside a cavity [2], or placed in front of a single mirror [3] or even in free space without any mirrors [4].

Biexcitonic effects in coherently controlled six-wave-mixing experiments on ZnSe quantum wells

Hans Georg Breunig, T. Voss, Ilja Rückmann +1 more

Coherently controlled four-wave-mixing (FWM) measurements have turned out to be a very sensitive tool to investigate the microscopic origin of the nonlinear optical response of semiconductor quantum-well structures, in particular if excitons are excited [1-3]. The measured signal oscillates as a function of the phase difference of the two interferometric pulses and is modulated additionally by contributions that oscillate with integer multiples of the excitonic resonance frequency. The influence of these harmonics can be measured in background free directions, i.e., the first (FWM) or second (six-wave mixing, SWM) diffracted order in direction 2k2-k1 or 3k2-2k1, respectively. Their intensity is easily quantified by inspecting the corresponding Fourier transforms (FT). Here, we report on transient interferometric SWM measurements and the influence of biexcitons on the signal.
