On-chip pulse generation at 8 μm wavelength
Annabelle Bricout, Mathieu Bertrand, Philipp Täschler +15
The mid-infrared spectral region holds growing importance for applications such as gas sensing and spectroscopy. Although compact ultrashort pulse laser sources are essential to en…
Germanium-Based Mid-Infrared Photonics
Delphine Marris-Morini, Goran Z. Mashanovich, Milos Nedeljkovic +4
The mid-infrared (mid-IR) spectral range is a part of the electromagnetic spectrum in which most of the molecules have vibrational and rotational resonances. Ge-based photonic inte…
Second harmonic generation in germanium quantum wells for nonlinear silicon photonics
Jacopo Frigerio, Chiara Ciano, Joel Kuttruff +12
Second-harmonic generation (SHG) is a direct measure of the strength of second-order nonlinear optical effects, which also include frequency mixing and parametric oscillations. Nat…
Dissolution of donor-vacancy clusters in heavily doped n-type germanium
Slawomir Prucnal, Maciej O. Liedke, Xiaoshuang Wang +17
The n-type doping of Ge is a self-limiting process due to the formation of vacancy-donor complexes (DnV with n <= 4) that deactivate the donors. This work unambiguously demonstrate…
Optical modulation in Ge-rich SiGe waveguides in the mid-IR wavelength range up to 11 um
Miguel Montesinos-Ballester, Vladyslav Vakarin, Joan Manel Ramirez +11
Waveguide integrated optical modulators in the mid-infrared (mid-IR) wavelength range are of significant interest for molecular spectroscopy in one hand, as on-chip synchronous det…
Assessing the potential of Ge/SiGe quantum dots as hosts for singlet-triplet qubits
Andrea Hofmann, Daniel Jirovec, Maxim Borovkov +6
We study double quantum dots in a Ge/SiGe heterostructure and test their maturity towards singlet-triplet () qubits. We demonstrate a large range of tunability, from two sin…
