摘要

We report the photocurrent and differential absorption spectra of an InGaAsN single- and a double-quantum-well (SQW and DQW) structure measured at different reverse bias. The DQW structure shows an additional enhancement in electroabsorption of a maximum /spl Delta//spl alpha/ /spl sim/ 14400 cm/sup -1/, which is 2.6 times larger than the maximum /spl Delta//spl alpha/ /spl sim/ 5400 cm/sup -1/ of the SQW sample.
