摘要：

Blue shift of the heavy-hole peak of the photocurrent spectra has been observed, for the first time, in narrow GaAs/Al0.4Ga0.6As asymmetric coupled quantum wells near the heavy-hole resonance. With an external reverse bias of only -2.35 V, a maximum upward shift of the apparent peak position of approximately 6.1 meV has been measured at 78 K. Sharp change of the inhomogeneous linewidth of the heavy-hole peak has also been observed. cw optical bistability has been observed with the external feedback.
