Daniela Stange,Stephan Wirths,R. Geiger,C. Schulte-Braucks,Bahareh Marzban,Nils von den Driesch,Gregor Mussler,T. Zabel,Toma Stoica,J. M. Hartmann,Siegfried Mantl,Zoran Ikonic,Detlev Grützmacher,Hans Sigg,Jeremy Witzens,Dan Buca +15 more
TL;DR: In this paper, a group IV microdisk laser with significant improvements in lasing temperature and lasing threshold compared to the previously reported nonundercut Fabry-Perot type lasers is presented.
Journal ArticleDOI
Optically pumped GeSn micro-disks with 16 % Sn lasing at 3.1 um up to 180K
V. Reboud,Alban Gassenq,Nicolas Pauc,J. Aubin,L. Milord,Q. M. Thai,Mathieu Bertrand,Kevin Guilloy,D. Rouchon,J. Rothman,T. Zabel,F. Armand Pilon,H. Sigg,A. Chelnokov,J.M. Hartmann,V. Calvo +15 more
TL;DR: In this article, the authors reported a longer emitted wavelength and a significant improvement in lasing temperature using higher Sn content GeSn layers of optimized crystalline quality, grown on graded Sn content buffers using Reduced Pressure CVD.

Journal ArticleDOI
Silicon photonic crystal nanostructures for refractive index sensing
Dominic F. Dorfner,T. Hürlimann,T. Zabel,Lars Hagedorn Frandsen,Gerhard Abstreiter,Jonathan J. Finley +5 more
TL;DR: In this article, two defect nanocavities (L3 and H1−r) are embedded between two W1 photonic crystal waveguides to evanescently route light at the cavity mode frequency between input and output waveguide.
Journal ArticleDOI
Group IV direct band gap photonics: Methods, Challenges and Opportunities
R. Geiger,T. Zabel,Hans Sigg +2 more
TL;DR: The concept of direct band gap group IV materials offers a paradigm change for Si-photonics concerning the monolithic implementation of light emitters: the idea is to integrate fully compatible group IV material with equally favorable optical properties as the chemically incompatible group III-V-based systems.
