quantum-confined Franz-Keldysh effect in semiconductor quantum wires and dots," Appl.
Phys. Lett., 52, 2154-2156, (1988).
Semiconductor quantum wells are known
to show large electroabsorption (e.g., the quantum-confined Stark effect) that results in
a low-energy optical modulating and switching devices. we show theoretically that the
electroabsorption and associated electrorefraction in lower dimensional structures could
be much larger, suggesting very low energy devices. We illustrate the theory with specific
calculations for hypothetical GaAs-like quantum wires and dots.
