Abstract

Experimental observations of the coherently coupled optical Stark effect in InGaAs quantum wells were presented. Theoretical analysis was based on a full many-body theory within the third-order nonlinear optical regime. Stark shift data was shown to provide evidence of suitably defined nonradiative intervalence band coherences in the quantum well.
