in self-electro-optic effect devices with asymmetric quantum wells," Appl. Phys.
Lett., 54, 202-204, (1988).
It is shown theoretically that optical
bistability is possible in a self-electro-optic effect device (SEED) with single
asymmetric quantum wells because of the blue shift of the optical absorption edge with
applied field possible in such structures (in contrast to the normal red shift in
symmetric wells). The concept is a simplification of the scheme of J. Khurgin (Appl. Phys.
Lett. 53, 779 (1988)) (which uses unequal, opposed pairs of asymmetric wells) and shares
the potential advantages of lower loss in the transmitting state and less stringent
requirements on the exciton absorption peaks
