Abstract
Calculation shows that the bandgap resonant nonlinear susceptibility in a multi-quantum-well structure can be a factor of approximately 2 greater than in the bulk. The calculation uses the mechanism of blocking of band-to-band transitions, likely to be present in materials of interest for advanced optical-fibre communication systems.
