Single-photon emission of InAs/InP quantum dashes at 1.55 μm and temperatures up to 80 K
(2016-04-18) - Journal article
We report on single photon emission from a self-assembled InAs/InGaAlAs/InP quantum dash emitting at 1.55 µm at elevated temperatures. The photon auto-correlation histograms of the emission from a charged exciton indicate ...
Influence of carrier concentration on properties of InAs waveguide layers in interband cascade laser structures
(2016-07-28) - Journal article
We present a characterization of doped InAs layers in interband cascade lasers exploiting the plasmon-enhanced waveguiding. Fast differential reflectance was employed in order to identify the plasma-edge frequency via the ...
On-chip light detection using monolithically integrated quantum dot micropillars
(2016-02-22) - Journal article
We demonstrate the on-chip detection of light using photosensitive detectors based on quantum dot (QD) micropillar cavities. These microscale detectors are applied exemplarily to probe the emission of a monolithically ...
Half adder capabilities of a coupled quantum dot device
(2016-05-27) - Journal article
In this paper we demonstrate two realizations of a half adder based on a voltage-rectifying mechanism involving two Coulomb-coupled quantum dots. First, we examine the ranges of operation of the half adder's individual ...
Talbot effect for exciton-polaritons
(2016-08-26) - Journal article
We demonstrate, experimentally and theoretically, a Talbot effect for hybrid light-matter waves - exciton-polariton condensate formed in a semiconductor microcavity with embedded quantum wells. The characteristic `Talbot ...
