Roadmap to an Efficient Germanium-on-Silicon Laser: Strain vs. n-Type Doping
We provide a theoretical analysis of the relative merits of tensile strain and n-type doping as approaches to realizing an efficient low-power germanium laser. Ultimately, tensile strain offers threshold reductions of over 200x, and significant improvements in slope efficiency compared with the rece...
