Controlled light shaping via phase dependent electromagnetically induced transparency

Abstract

We explore optical manipulation of sculpted light based on phase dependent electromagnetically induced transparency through a five level atomic system. A transverse magnetic field (TMF) and a suitable spatially inhomogeneous control field can be used to create a spatial probe transparency modulation at a desired location. Such transparency modulation is the principle behind the shaping of the light. Further the beam propagation equation shows that the control field induced selective phase information can be imprinted on the probe beam. Hence this controlled light shaping paves a new way for optical tweezers, high contrast imaging and micromachining.
