Germanium microring avalanche photodetector for 2 μm wavelengths
Waveguide-coupled Ge avalanche photodetector operating at 2 μm wavelength was demonstrated on GeOI platform. Thanks to microring resonator and avalanche gain, we achieved 2.18 A/W responsivity at -11 V and clear eye diagram at 2.5 Gbit/s, proving the potential of GeOI for mid-infrared photonics applications.
