Abstract :
Strain-compensated p-type SiGe quantum cascade (QC) structures are promising candidates to realize an efficient Si-based light source. In this paper, we present the strategies to improve the optical gain and to minimize the waveguide loss to develop a SiGe QC laser for mid-infrared wavelength
