Paper Abstract

Enhancement of higher order nonlinear susceptibilities are investigated in three level quantum well with a ladder configuration in the regime of electromagnetically induced transparency. We have identified the existence of giant third and fifth order nonlinear susceptibilities of the order ~10-22 m4/V4 at pump wavelength of 9.6 μm. The group velocity is reported to be slowed down by 104 times compared to the speed of light in vacuum.
