We report the first measurements of the quantum confined Stark effect in single GaInAs/InP quantum wells using photocurrent spectra from a single 80 Å well. Well resolved excitonic features are observed for values of electric field up to 3 × 105 V/cm, whose field dependent shift and peak height are in excellent agreement with the predictions of an effective mass calculation, thus demonstrating that there are no intrinsic factors limiting this effect in the GaInAs/InP material system.
