Inducing electron spin coherence in GaAs quantum well waveguides: spin coherence without spin precession

Electron spin coherence is induced via light-hole transitions in a quantum well waveguide without a DC magnetic field. The spin coherence is detected through effects of quantum interference in spectral domain nonlinear optical response.
