Linear and Nonlinear Intersubband Optical Properties of Direct Band Gap GeSn Quantum Dots
Intersubband optical transitions, refractive index changes, and absorption coefficients are numerically driven for direct bandgap strained GeSn/Ge quantum dots. The linear, third-order nonlinear and total, absorption coefficients and refractive index changes are evaluated over useful dot sizes’ rang...
