摘要:

Strategies designed to optimize the performance of the multi-quantum well stack in optical modulator devices based on the quantum-confined Stark effect can be derived from an observation that the effective mass of the active quantum well material is significantly smaller in the conduction band than that in the valence band. This suggests that significant improvements in the overall performance of the devices may be achieved by engineering the band alignment of quantum well and barrier to accommodate the difference in the effective masses. ©1997 American Institute of Physics.
