Fourier transform (FT) analysis is applied to electromodulation data for circumstances in which Franz-Keldysh oscillations (FKO) dominate the optical spectrum. It is shown that the FT analysis simplifies the procedure for obtaining the electric fields from the FKO's. In addition, an internal check is provided by virtue of the fact that both light and heavy hole contributions to the optical spectrum are resolved in the transformed data. Applications to various device structures are considered from simple structures optimized for the FKO effect to HEMTs and HBTs.
