Increased quadratic electro-optic effect in GaAs/AlGaAs square quantum wells
28 October 1999
The linear and quadratic electro-optic coefficients of 6nm wide GaAs/Al0.2Ga0.8As quantum wells have been measured over a wide range of detuned energies. The quadratic coefficient is found to be about twice that reported for wider and deeper quantum wells for both TE and TM polarisations.
