text: AbstractSpin‐controlled lasers are highly
interesting photonic devices and have been shown to provide ultrafast polarization
dynamics in excess of 200 GHz. In contrast to conventional semiconductor lasers
their temporal properties are not limited by the intensity dynamics, but are governed
primarily by the interaction of the spin dynamics with the birefringent mode splitting
that determines the polarization oscillation frequency. Another class of modern
semiconductor lasers are high‐β emitters, which benefit
from enhanced light–matter interaction due to strong mode confinement in low‐mode‐volume
microcavities. In such structures, the emission properties can be tailored by
the resonator geometry to realize for instance bimodal emission behavior in slightly
elliptical micropillar cavities. This attractive feature is utilized to demonstrate
and explore spin‐lasing effects in bimodal high‐β quantum
dot micropillar lasers. The studied microlasers with a β‐factor
of 4% show spin‐laser effects with experimental polarization oscillation frequencies
up to 15 GHz and predicted frequencies up to about 100 GHz, which are controlled
by the ellipticity of the resonator. These results reveal appealing prospects
for very compact, ultrafast, and energy‐efficient spin‐lasers and can pave the
way for future purely electrically injected spin‐lasers enabled by short injection
path lengths.

text: We have investigated the stacking of self-assembled cubic GaN quantum dots
(QDs) grown in Stranski–Krastanov (SK) growth mode. The number of stacked layers
is varied to compare their optical properties. The growth is in situ controlled
by reflection high energy electron diffraction to prove the SK QD growth. Atomic
force and transmission electron microscopy show the existence of wetting layer
and QDs with a diameter of about 10 nm and a height of about 2 nm. The QDs have
a truncated pyramidal form and are vertically aligned in growth direction. Photoluminescence
measurements show an increase of the intensity with increasing number of stacked
QD layers. Furthermore, a systematic blue-shift of 120 meV is observed with increasing
number of stacked QD layers. This blueshift derives from a decrease in the QD
height, because the QD height has also been the main confining dimension in our
QDs.

text: "We analyse an InAs/GaAs-based electric field tunable single quantum dot diode
with a thin tunnelling barrier between a\r\nburied n þ -back contact and a quantum
dot layer. In voltage- dependent photoluminescence measurements, we observe rich
signatures from spatially direct and indirect transitions from the wetting layer
and from a single quantum dot. By analysing the Stark effect, we show that the
indirect transitions result from a recombination between confined holes in the
wetting or quantum dot layer with electrons from the edge of the Fermi sea in
the back contact. Using a 17 nm tunnel barrier which provides comparably weak
tunnel coupling allowed us to observe clear signatures of direct and corresponding
indirect lines for a series of neutral and positively charged quantum dot states."

text: Here we report on investigations on CdSe quantum dots incorporated in ZnSe
based Schottky photodiodes with near-field shadow masks. Photoluminescence and
photocurrent of individual quantum dots were studied as a function of the applied
bias voltage. The exciton energy of the quantum dot ground state transition was
shifted to the excitation energy by using the Stark effect tuning via an external
bias voltage. Under the condition of resonance with the laser excitation energy
we observed a resonant photocurrent signal due to the tunnelling of carriers out
of the quantum dots at electric fields above 500 kV/cm.
