Abstract
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.
