Electroabsorption modulation in strained piezoelectricInGaAs/InP multiquantum wells operating at λ ≃ 1.55 µm

Abstract
An investigation of absorption modulation using strained piezoelectric InGaAs/InP multiquantum wells grown on (111)B InP substrates is presented. Strong excitonic features are observed in the room temperature photocurrent spectra for a structure with 50 Å quantum wells under 0.6% compressive strain. The application of a reverse bias results in a large blue-shift of the absorption edge of up to 8 nm/V.
