Monolithic Infrared Silicon Photonics: The Rise of (Si)GeSn Semiconductors
Oussama Moutanabbir, Simone Assali, Xiao Gong +9
(Si)GeSn semiconductors are finally coming of age after a long gestation period. The demonstration of device quality epi-layers and quantum-engineered heterostructures has meant th…
Design of a waveguide-coupled GeSn disk laser
Bahareh Marzban, Jovana Nojic, Daniela Stange +2
We report on the design of a waveguide coupled GeSn microdisk-laser cavity in which the germanium virtual substrate serving as a template for GeSn growth is repurposed for the defi…
Ultra-low threshold cw and pulsed lasing in tensile strained GeSn alloys
A. Elbaz, D. Buca, N. Von den Driesch +15
GeSn alloys are the most promising semiconductors for light emitters entirely based on group IV elements. Alloys containing more than 8 at.% Sn have fundamental direct band-gaps, s…
Fabrication of comb-drive actuators for straining nanostructured suspended graphene
M. Goldsche, G. J. Verbiest, T. Khodkov +4
We report on the fabrication and characterization of an optimized comb-drive actuator design for strain-dependent transport measurements on suspended graphene. We fabricate devices…
