摘要：

We have studied optical switching of transmission-type self-electro-optic effect devices (SEEDs) based on Wannier-Stark localization (WSL) in a GaAs/AlAs superlattice (SL). Switching properties of both resister-biased and symmetric SEED are investigated as a function of operation wavelength. Clear optical bistability between two stable transmission states is obtained in the S-SEED configuration using the WSL. The detailed results of optical switching experiments are presented and explained in terms of a blue-shift mechanism of the optical absorption edge and an additional absorption mechanism due to spatially indirect Stark-ladder transitions in the SL. The SEED operation with a high transmission state is also demonstrated, and the advantages of the WSL are discussed for application to vertical transmission photonic switches.
