In GaAs, we observe experimentally strong electric field effects on the optical second (SHG) and third (THG) harmonic generation. The SHG signal for the laser-light k vector parallel to the [001] crystal axis is symmetry forbidden in the electric-dipole approximation, but can be induced by an applied electric field in the vicinity of the 1s exciton energy. Surprisingly, the THG signal, which is allowed in this geometry, is considerably reduced by the electric field. We develop a theory which provides good agreement with the experimental data. In particular, it shows that the optical nonlinearities for the 1s exciton resonance are modified in an electric field by the Stark effect, which mixes the 1s and 2p exciton states of opposite parity. This mixing acts in opposite way on the SHG and THG processes, as it leads to the appearance of forbidden SHG in (001)-oriented GaAs and decreases the crystallographic THG. article_type: original author: - first_name: D. full_name: Brunne, D. last_name: Brunne - first_name: M. full_name: Lafrentz, M. last_name: Lafrentz - first_name: V.

The modulation of the emission wavelength takes place on the frequencies of the nanomechanical extensional and breathing (radial) modes of the micropillars. The amplitude of the modulation for various nanomechanical modes is different for every micropillar which is explained by a various elastic contact between the micropillar walls and polymer environment. article_number: '041103' article_type: original author: - first_name: T. full_name: Czerniuk, T. last_name: Czerniuk - first_name: J. full_name: Tepper, J. last_name: Tepper - first_name: A.

Both the intensity and the photon number statistics of the emission from the micropillar show a strong dependence on the photon statistics of the light used for excitation of the sample. The results under coherent and pseudothermal excitation reveal that a description of the laser properties in terms of mean input photon numbers is not sufficient. It is demonstrated that the micropillar acts as a superthermal light source when operated close to its threshold. Possible applications for important spectroscopic techniques are discussed. article_type: original author: - first_name: T. full_name: Kazimierczuk, T. last_name: Kazimierczuk - first_name: J. full_name: Schmutzler, J. last_name: Schmutzler - first_name: M. full_name: Aßmann, M. last_name: Aßmann - first_name: C. full_name: Schneider, C. last_name: Schneider - first_name: M. full_name: Kamp, M. last_name: Kamp - first_name: S. full_name: Höfling, S. last_name: Höfling - first_name: M. full_name: Bayer, M. last_name: Bayer citation: ama: Kazimierczuk T, Schmutzler J, Aßmann M, et al.

The phonon density of states of the ferroelectric (paraelectric) phase shows two (one) distinct band gaps separating the high-frequency (~800 cm−1) optical branches from the continuum of acoustic and lower optical phonon states. This result leads to specific heat capacites in close agreement with experimental measurements in the range 0–350 K and a Debye temperature of 574 K. The calculated zero-point renormalization of the electronic Kohn–Sham eigenvalues reveals a strong dependence on the phonon wave vectors, especially near Γ. Integrated over all phonon modes, our results indicate a vibrational correction of the electronic band gap of 0.41 eV at 0 K, which is in excellent agreement with the extrapolated temperature-dependent measurements. article_number: '385402' article_type: original author: - first_name: Michael full_name: Friedrich, Michael last_name: Friedrich - first_name: Arthur full_name: Riefer, Arthur last_name: Riefer - first_name: Simone full_name: Sanna, Simone last_name: Sanna - first_name: Wolf Gero full_name: Schmidt, Wolf Gero id: '468' last_name: Schmidt orcid: 0000-0002-2717-5076 - first_name: Arno full_name: Schindlmayr, Arno id: '458' last_name: Schindlmayr orcid: 0000-0002-4855-071X citation: ama: 'Friedrich M, Riefer A, Sanna S, Schmidt WG, Schindlmayr A.

One of the most common components of such type \r\nis the opto-electrical receiver. The monolithic implementation of the receiver could potentially have lower \r\npower consumption, higher sensitivity and bandwidth due to very short diode to amplifier connection \r\nlength, which has very low parasitic capacitance and series resistance. The SiGe photodiode itself is also \r\nvery compact, thus lowering the junction capacitance and improving its bandwidth. Among the different optical communication systems, coherent transmission lately received a lot of \r\nattention due to the rising requirements of the optical link capacity, and it was shown that this particular \r\napproach could benefit greatly from the monolithic integration, since the major component required for the \r\ndemodulation on the receiver side – 90° optical hybrid – could be implemented fully passive and directly \r\non the same chip as the receiver itself, together with digital post-processing circuitry. Despite the initial \r\ncomplexity of the modulation scheme, advanced silicon photonics components like this optical hybrid \r\ncould make coherent transmission attractive even for short-range optical links. I would like to present the actual designs, implementation and measurement results of 90° fully passive \r\noptical hybrids, implemented in the IHP SG25PIC (passive photonics IC) technology. One of the designs \r\nis based on 4x4 multimode interferometer (MMI). The other one is based on two separate 2x2 MMIs with \r\nadditional delay element. The final designs didn’t require any additional tuning after fabrication and have \r\nshown sufficient precision and performance for a coherent system design. The results of this work were \r\nlater used for the design of monolithic coherent receiver." author: - first_name: Sergiy full_name: Gudyriev, Sergiy last_name: Gudyriev - first_name: Christoph full_name: Scheytt, Christoph id: '37144' last_name: Scheytt orcid: https://orcid.org/0000-0002-5950-6618 citation: ama: 'Gudyriev S, Scheytt C.
