文摘The optical properties of germanium can be tailored by combining strain engineering and n-type doping.In this paper,we review the recent progress that has been reported in the study of germanium light emitters for silicon photonics.We discuss the different approaches that were implemented for strain engineering and the issues associated with n-type doping.We show that compact germanium emitters can be obtained by processing germanium into tensile-strained microdisks.
