Low-threshold optically pumped lasing in highly strained Ge nanowires
Shuyu Bao, Daeik Kim, Chibuzo Onwukaeme +11
The integration of efficient, miniaturized group IV lasers into CMOS architecture holds the key to the realization of fully functional photonic-integrated circuits. Despite several…
Anomalous Threshold Reduction from <100> Uniaxial Strain for a Low-Threshold Ge Laser
David S. Sukhdeo, Shashank Gupta, Krishna C. Saraswat +2
We theoretically investigate the effect of <100> uniaxial strain on a Ge-on-Si laser using deformation potentials. We predict a sudden and dramatic ~200x threshold reduction upon a…
Theoretical Modeling for the Interaction of Tin alloying with N-Type Doping and Tensile Strain for GeSn Lasers
David S. Sukhdeo, Krishna C. Saraswat, Birendra +2
We investigate the interaction of tin alloying with tensile strain and n-type doping for improving the performance of a Ge-based laser for on-chip optical interconnects. Using a mo…
