Abstract

We present intersubband absorption in the conduction band of compressively strained germanium quantum wells bounded by Ge-rich SiGe barriers. The measured absorption energies are in the 5-12 THz range depending on the well width. These results may be relevant for the design of SiGe-based THz Quantum Cascade emitters.
