Enhanced electrorefraction in symmetric narrow coupled quantum wells

The quadratic electrooptic coefficient of narrow symmetric-coupled GaAs-Al/sub 0.2/Ga/sub 0.8/As quantum wells has been measured for light having a range of detuned wavelengths with TE polarization and is found to be 2-3 times larger than that of single quantum wells equivalent overall width.
