Optical orientation of hole magnetic polarons in (Cd,Mn)Te/(Cd,Mn,Mg)Te quantum wells

Optical Physics of Quantum Wells

Quantum wells are thin layered semiconductor structures in which we can observe and control many quantum mechanical effects. They derive most of their special properties from the quantum confinement of charge carriers (electrons and "holes") in thin layers (e.g 40 atomic layers thick) of one semiconductor "well" material sandwiched between other semiconductor "barrier" layers. They can be made ...

Strong Optical Filed Intensity Improvement Introducing InGaAsP Quantum Wells in InP Nanocavity

This paper presents the optical characteristics of a quantum well doped InP nanocavity.The resonance wavelength of the nanocavity and the optical field intensity is calculated before and after presence of the quantum wells. The resulting huge filed intensity of about 1.2×108 respect to the incident field is the effect of quantum wells placed in vicinity of center of nanocavity.

Subpicosecond excitonic optical nonlinearities in quantum wells

2014 Excitonic resonances in semiconductors are very sensitive to applied optical fields. We present here a comparison between the effects of resonant and non resonant optical excitation, creating respectively real or virtual excitons. A blue shift of the exciton line and a reduction of the oscillator strength are simultaneously observed in multiple-quantum-well-structures for the two following...
