Over the last decade Ge has been proposed as one of the most promising materials for light detection, modulation, and emission in silicon-photonics architectures. Its direct band-gap, which is only about 140 meV larger than the indirect one, ensures

We experimentally investigate the smallest germanium waveguide cavity resonators on silicon that can be designed to work around 1.55 mu m wavelength and observe an almost 30-fold enhancement in the collected spontaneous emission per unit volume when
