Abstract: Provided is a germanium photodetector having a germanium epitaxial layer formed without using a buffer layer and a method of fabricating the same. In the method, an amorphous germanium layer is formed on a substrate. The amorphous germanium layer is heated up to a high temperature to form a crystallized germanium layer. A germanium epitaxial layer is formed on the crystallized germanium layer.

Abstract: The inventive concept provides semiconductor laser devices and methods of fabricating the same. According to the method, a silicon-crystalline germanium layer for emitting a laser may be formed in a selected region by a selective epitaxial growth (SEG) method. Thus, surface roughness of both ends of a Fabry Perot cavity formed of the silicon-crystalline germanium layer may be reduced or minimized, and a cutting process and a polishing process may be omitted in the method of fabricating the semiconductor laser device.
