Abstract

We have developed and used transient three-pulse differential absorption spectroscopy to probe and control the fifth order nonlinear optical response induced by electron spin coherence in GaAs quantum wells.

Vanishing and Emerging of Absorption Quantum Beats from Electron Spin Coherence in GaAs Quantum Wells

Phedon Palinginis, Hailin Wang

We report experimental studies of absorption quantum beats induced by electron spin coherence in GaAs quantum wells. Absorption quantum beats occur for strongly localized excitons, but nearly vanish for mobile excitons in the third order nonlinear optical response. Pronounced quantum beats for mobile excitons emerge in an unusual fifth order process. These results, along with a qualitative analysis based on the use of N-exciton eigenstates, elucidate how the manifestation of electron spin coherence in the excitonic nonlinear optical response can differ fundamentally from that in an atomic system.

Coherent spin dynamics of donor bound electrons in GaAs

Carey E. Phelps, Shannon O’Leary, John P. Prineas +1 more

We report experimental studies of coherent spin dynamics of donor-bound electrons in high-purity GaAs by using transient differential transmission. The donor-bound exciton transitions, which are not visible in the linear absorption spectrum, are spectrally resolved in the nonlinear differential transmission spectra. The spin beats in the transient differential transmission response, arising from electron spin precession in an external magnetic field, are investigated with the pump and probe coupling to various donor-bound exciton transitions. The spectral dependence of the spin beats provides important information on the polarization selection rule for the underlying donor-bound exciton transitions. The polarization selection rules deduced from these experiments indicate that contributions from higher-energy donor-bound exciton transitions can severely limit the effectiveness of optical spin control using mechanisms such as polarization-dependent optical Stark shifts.

Coherent Raman resonance from electron spin coherence in GaAs quantum wells

Phedon Palinginis, Hailin Wang

We report the experimental demonstration of coherent Raman resonance from electron spin coherence in $\mathrm{GaAs}$ quantum wells. Coherent Raman resonance, which is a precursor for electromagnetically induced transparency, appears in the differential transmission response from localized excitons in an external magnetic field applied in Voigt geometry. The spectral domain spin study reveals that the optical processes involved differ from those in the transient domain, leading to distinct polarization and intensity dependences.
