Paper Abstract

Multiple triple quantum wells (TQWs) are used in the active region of an AlGaAs p-i-n diode for a reflection modulator operating above the GaAs band gap. Photocurrent spectra of the TQW-based diode show sharp absorption features that retain their spectral character with reverse bias and show large Stark shifts--comparable to those obtained from alternative active-layer designs. Some performance characteristics of an 810-nm reflection modulator using the TQW active-layer design are presented. We also describe time-resolved pump/probe measurements made on a series of TQW-based p-i-n diodes with differing p-layer conductivity and contrast results with the predictions of a simplified model of the carrier dynamics.
