text: Superconducting nanowire single-photon detectors (SNSPDs) show near
unity efficiency, low dark count rate, and short recovery time. Combining these
characteristics with temporal control of SNSPDs broadens their applications as
in active de-latching for higher dynamic range counting or temporal filtering
for pump-probe spectroscopy or LiDAR. To that end, we demonstrate active gating
of an SNSPD with a minimum off-to-on rise time of 2.4 ns and a total gate length
of 5.0 ns. We show how the rise time depends on the inductance of the detector
in combination with the control electronics. The gate window is demonstrated to
be fully and freely, electrically tunable up to 500 ns at a repetition rate of
1.0 MHz, as well as ungated, free-running operation. Control electronics to generate
the gating are mounted on the 2.3 K stage of a closed-cycle sorption cryostat,
while the detector is operated on the cold stage at 0.8 K. We show that the efficiency
and timing jitter of the detector is not altered during the on-time of the gating
window. We exploit gated operation to demonstrate a method to increase in the
photon counting dynamic range by a factor 11.2, as well as temporal filtering
of a strong pump in an emulated pump-probe experiment.

text: AbstractTailored nanoscale quantum light
sources, matching the specific needs of use cases, are crucial building blocks
for photonic quantum technologies. Several different approaches to realize solid-state
quantum emitters with high performance have been pursued and different concepts
for energy tuning have been established. However, the properties of the emitted
photons are always defined by the individual quantum emitter and can therefore
not be controlled with full flexibility. Here we introduce an all-optical nonlinear
method to tailor and control the single photon emission. We demonstrate a laser-controlled
down-conversion process from an excited state of a semiconductor quantum three-level
system. Based on this concept, we realize energy tuning and polarization control
of the single photon emission with a control-laser field. Our results mark an
important step towards tailored single photon emission from a photonic quantum
system based on quantum optical principles.

text: "Photonic quantum technologies [1] with applications in quantum\r\ncommunication,
sensing as well as quantum simulation and computing, are on the\r\nverge of becoming
commercially available. One crucial building block are\r\ntailored nanoscale integratable
quantum light sources, matching the specific\r\nneeds of use-cases. Several different
approaches to realize solid-state quantum\r\nemitters [2] with high performance
[3] have been pursued. However, the\r\nproperties of the emitted single photons
are always defined by the individual\r\nquantum light source and despite numerous
quantum emitter tuning\r\ntechniques [4-7], scalability is still a major challenge.
Here we show an\r\nemitter-independent method to tailor and control the properties
of the single\r\nphoton emission. We demonstrate a laser-controlled down-conversion
process from\r\nan excited state of a quantum three-level system [8]. Starting
from a biexciton\r\nstate, a tunable control laser field defines a virtual state
in a stimulated\r\nprocess. From there, spontaneous emission to the ground state
leads to\r\noptically controlled single photon emission. Based on this concept,
we\r\ndemonstrate energy tuning of the single photon emission with a control laser\r\nfield.
The nature of the involved quantum states furthermore provides a unique\r\nbasis
for the future control of polarization and bandwidth, as predicted by\r\ntheory
[9,10]. Our demonstration marks an important step towards tailored\r\nsingle photon
emission from a photonic quantum system based on quantum optical\r\nprinciples."

text: Potassium titanyl phosphate (KTP) is a nonlinear optical material
with applications in high-power frequency conversion or quasi-phase matching in
submicron period domain grids. A prerequisite for these applications is a precise
control and understanding of the poling mechanisms to enable the fabrication of
high-grade domain grids. In contrast to the widely used material lithium niobate,
the domain growth in KTP is less studied, because many standard methods, such
as selective etching or polarization microscopy, provides less insight or are
not applicable on non-polar surfaces, respectively. In this work, we present results
of confocal Raman-spectroscopy of the ferroelectric domain structure in KTP. This
analytical method allows for the visualization of domain grids of the non-polar
KTP y-face and therefore more insight into the domain-growth and -structure in
KTP, which can be used for improved domain fabrication.

text: In our work, we have engineered low capacitance single quantum dot photodiodes
as sensor devices for the optoelectronic sampling of ultrafast electric signals.
By the Stark effect, a time-dependent electric signal is converted into a time-dependent
shift of the transition energy. This shift is measured accurately by resonant
ps laser spectroscopy with photocurrent detection. In our experiments, we sample
the laser synchronous output pulse of an ultrafast CMOS circuit with high resolution.
With our quantum dot sensor device, we were able to sample transients below 20
ps with a voltage resolution in the mV-range.

text: "In recent years, Raman spectroscopy has been used to visualize and analyze
ferroelectric domain structures.\r\nThe technique makes use of the fact that the
intensity or frequency of certain phonons is strongly influenced\r\nby the presence
of domain walls. Although the method is used frequently, the underlying mechanism
responsible\r\nfor the changes in the spectra is not fully understood. This inhibits
deeper analysis of domain structures based\r\non this method. Two different models
have been proposed. However, neither model completely explains all\r\nobservations.
In this work, we have systematically investigated domain walls in different scattering
geometries\r\nwith Raman spectroscopy in the common ferroelectric materials used
in integrated optics, i.e., KTiOPO4,\r\nLiNbO3, and LiTaO3. Based on the two models,
we can demonstrate that the observed contrast for domain\r\nwalls is in fact based
on two different effects. We can identify on the one hand microscopic changes
at the\r\ndomain wall, e.g., strain and electric fields, and on the other hand
a macroscopic change of selection rules at the\r\ndomain wall. While the macroscopic
relaxation of selection rules can be explained by the directional dispersion\r\nof
the phonons in agreement with previous propositions, the microscopic changes can
be explained qualitatively\r\nin terms of a simplified atomistic model."

text: "We report on the coherent phase manipulation of quantum dot excitons by electric
means. For our\r\nexperiments, we use a low capacitance single quantum dot photodiode
which is electrically\r\ncontrolled by a custom designed SiGe:C BiCMOS chip. The
phase manipulation is performed and\r\nquantified in a Ramsey experiment, where
ultrafast transient detuning of the exciton energy is\r\nperformed synchronous
to double pulse p/2 ps laser excitation. We are able to demonstrate\r\nelectrically
controlled phase manipulations with magnitudes up to 3p within 100 ps which is

text: In this article we demonstrate a fully CMOS compatible fabrication process
for the realization of microdisk resonators based on silicon oxynitride. The layer
fabrication using plasma enhanced chemical vapor deposition is optimized in terms
of surface roughness and internal material absorption. Resulting surface roughness
due to the etching process is reduced by using optimized etching parameters. Whispering
gallery modes of the fabricated microdisk resonators have been investigated by
tapered fiber coupling and show quality factors as high as 10 6.

text: In this work we study the impact of ion implantation on the nonlinear optical
properties in MgO:LiNbO3 via confocal second-harmonic microscopy. In detail, we
spatially characterize the nonlinear susceptibility in carbon-ion implanted lithium
niobate planar waveguides for different implantation energies and fluences, as
well as the effect of annealing. In a further step, a computational simulation
is used to calculate the implantation range of carbon-ions and the corresponding
defect density distribution. A comparison between the simulation and the experimental
data indicates that the depth profile of the second-order effective nonlinear
coefficient is directly connected to the defect density that is induced by the
ion irradiation. Furthermore it can be demonstrated that the annealing treatment
partially recovers the second-order optical susceptibility.

text: "Semiconductor quantum dots are promising sources for polarization-entangled
photons. As an alternative\r\nto the usual cascaded biexciton-exciton emission,
direct two-photon emission from the biexciton can be used.\r\nWith a high-quality
optical resonator tuned to half the biexciton energy, a large proportion of the
photons\r\ncan be steered into the two-photon emission channel. In this case the
degree of polarization entanglement is\r\ninherently insensitive to the exciton
fine-structure splitting. In the present work we analyze the biexciton emission\r\nwith
particular emphasis on the influence of coupling of the quantum-dot cavity system
to its environment.\r\nEspecially for a high-quality cavity, the coupling to the
surrounding semiconductormaterial can open up additional\r\nphonon-assisted decay
channels. Our analysis demonstrates that with the cavity tuned to half the biexciton
energy,\r\nthe potentially detrimental influence of the phonons on the polarization
entanglement is strongly suppressed—high\r\ndegrees of entanglement can still
be achieved. We further discuss spectral properties and statistics of the emitted\r\ntwin
photons."
