Transient behavior of exciton resonances in InGaAs/InP QWs studied by a widely tunable femtosecond source

Not Accessible

Your library or personal account may give you access


Semiconductor multiple-quantum well (MQW) structures with InGaAs wells lattice-matched to InP barriers have attracted much attention because of applications in optoelectronics devices compatible with fiber-optics systems. The growth and the optical characterization of these heterostructures are still topics of extensive research aimed at understanding electronic properties and improveing material quality. Further, only a few measurements of the optical properties have been performed on a femtosecond time scale1, mainly because of a lack of widely tunable infrared laser sources.
