Abstract : There is great interest in nonlinear optical phenomena in a quantum well structure. Although there are various energy levels in the quantum well structure, most of nonlinear devices with the quantum well structure only utilize either interband or intraband electron transition. The interband transition is the transition from a valence band to a conduction band, and the intraband transition is the transition between the first and the second quantized energy levels in a conduction or a valence band. When we utilize both of the interband- and the intraband-transitions simultaneously, the freedom of the device synthesis is greatly increased, and light-controlled optical devices which are indispensable for the future optical signal processing and optical computing can be realized.
