Abstract

Room temperature amplified spontaneous emission at mid-IR has been observed from optically pumped GeSn waveguides on Si. For higher pump power, emission spectrum indicates the direct band to indirect band emission intensity ratio increases and the peak value increases nonlinearly due to the material gain.
