Study of the quantum-confined Stark effect in an unbiased [111]-oriented multi-quantum well semiconductor optical amplifier

Horacio Soto-Ortiz et al.

Summary: In this paper, a procedure and model for determining the electric field that governs the quantum-confined Stark effect in a multi-quantum well semiconductor optical amplifier were presented. The model accurately estimated the Stark shift of the excitonic resonances and demonstrated the presence of excitonic resonances in the amplifier. Additionally, the impact of modifying the strain in the quantum wells and the built-in electric field on the variability of the electric field was investigated.

Direct determination of the piezoelectric field using the quantum-confined Stark effect in a strained [111]-oriented zinc-blende MQW-SOA

Horacio Soto-Ortiz et al.

Summary: In this study, a method based on the quantum-confined Stark effect is presented to directly determine the piezoelectric field in strained zinc-blende quantum wells. The method is experimentally validated in a semiconductor optical amplifier and shows good agreement with theoretical predictions. The proposed technique offers a direct and reliable way to measure the piezoelectric field and can be applied to other structures with strained zinc-blende quantum wells.

Investigation of orientation dependence of piezoelectric effects in strained GaAs/InGaAs quantum well laser

Hosni Saidi et al.

Summary: This study investigates the influence of piezoelectric on the optical transition and laser-gain in GaAs/InGaAs quantum well. It is found that the piezoelectric changes the electronic band structure, leading to a decrease in optical transition and gain by about 50%.
