Optical Frequency Conductance, Susceptance and Admittance of Quantum Wells

Thomas Szkopek · IEEE Journal of Quantum Electronics · 2011

Optical absorption and emission via interband and intersubband transitions in a quantum well can be described by a quantized optical frequency conductance proportional to the fine structure constant. We present a compact physical model based on optical frequency admittance for the interaction of light with quantum wells in photodetectors and semiconductor lasers.
