Electroabsorption, or the Franz-Keldysh effect, has been measured in Ga0.24In0.76As0.52P0.48 with an energy gap of 1.03 eV. Absorption coefficients were determined by measuring the transmission versus bias through a double-heterostructure photodiode. The results are in good agreement with theory and are particularly applicable to modulators and detectors in the 1.25–1.30-μm band of interest in optical-fiber transmission.
Robert H. Kingston (1979) studied this question.
