Diffraction grating via position dependent incident light in a closed-loop quantum system

We have proposed a new model for controlling the electromagnetically induced grating in a three-level closed-loop quantum system. The quantum system interacts with three-laser fields which one of them is the weak probe light and two of them are strong driving and coupling laser fields. These two str...

Description
Summary:We have proposed a new model for controlling the electromagnetically induced grating in a three-level closed-loop quantum system. The quantum system interacts with three-laser fields which one of them is the weak probe light and two of them are strong driving and coupling laser fields. These two strong laser fields have standing wave (SW) patterns in two x and y directions. This makes that the absorption and dispersion properties of the media change periodically which leads to diffraction of the transmitted light. We have shown that because of the closed-loop configuration of the quantum system the relative phase between applied lights can affect the diffraction grating pattern of the transmitted light. We have also discussed the Rabi-frequency effect of the driving and coupling lights on the different orders of the grating. We have shown that our proposed model may be used as a new tool for developing the future quantum information processing devices.
