Abstract
We report results from a symmetric cavity electroabsorption modulator (SCEM) in GaAs/AlGaAs. A reflection change of approximately 45% with a n insertion loss of 1.3 dB is obtained under 7.5V in the normally-off mode. We discuss the factors that affect the device performance and co mpare the attainable performance with that of the normally-off asymmet ric Fabry-Perot modulator (AFPM). We also propose a new method for an improvement of the restricted tolerances of SCEMs. Finally, we demonst rate bistable operation using two SCEMs in the symmetric self-electroo ptic effect device (S-SEED) configuration, and attempt to evaluate the potential of this type of modulator for SEED applications.
