Towards low energy consumption integrated photonic circuits based on Ge/SiGe quantum wells
Despite being an indirect bandgap material, germanium (Ge) recently appeared as a material of choice for low power consumption optical link on silicon. Thanks to a low energy difference between direct and indirect energy bandgap, optical transitions around the direct gap can be used to achieve stron...
