Abstract
Asymmetric intra-step-barrier quantum wells (IQWs) are examined to show that an electric field directed from the deeper well to the step barrier can produce suppression in electroabsorption. The IQW electroabsorption modulator is shown experimentally to delay electroabsorption up to ~2.5 V. Preliminary optical saturation measurement of the modulator indicates that the RF link gain does not saturate up to ~12 dBm optical power
