Intersubband Optical Nonlinearity of GeSn Quantum Dots under Vertical Electric Field

Intersubband Optical Nonlinearity of GeSn Quantum Dots under Vertical Electric Field

The impact of vertical electrical field on the electron related linear and 3rd order nonlinear optical properties are evaluated numerically for pyramidal GeSn quantum dots with different sizes. The electric field induced electron confining potential profile’s modification is found to alter the trans...
