Abstract :
We have investigated the electro-optic effect for the vertically coupled InGaAs quantum dots. In addition to large TE-polarized electro-optic coefficient, TM-polarized electro-optic effect is observed. The linear and quadratic electro-optic coefficients are larger than GaAs-base multiple quantum well structures.
