Paper Abstract

The performance imitations have been studied for various optical bistable symmetric self-electrooptic effect devices (S-SEEDs) using extremely shallow quantum wells (ESQWs). We consider the four ESQW SEEDs; anti-reflection (AR)-coated ESQW S-SEED, back- to-back AR-coated ESQW S-SEED, asymmetric Fabry-Perot (AFP)-ESQW S-SEED, and back-to-back AFP-ESQW S-SEED. As the optical input power increases, the ohmic heating dominantly reduces the on- state reflectivity, while the exciton saturation dominantly increases the off-state reflectivity, both of which seriously degrade the device performances limiting the maximum input power for fast switching. For the quantitative estimation of the limitation, we simulate and analyze the bit-rates of the optically cascaded set-reset latch systems employing the various ESQW S-SEED. The optimized number of ESQWs for each structure is also obtained.
