Abstract :
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 Δα ∼ 14400 cm-1, which is 2.6 times larger than the maximum Δα ∼ 5400 cm-1 of the SQW sample.
