The characteristics of an electromagnetically induced grating (EIG) created in symmetric multiple quantum wells in the regime of electromagnetically induced transparency have been presented. The EIG is created due to absorption and phase modulation under the electromagnetically induced transparency. The increasing value of the Rabi frequency of control standing wave enhances transmission through the EIG. In addition, it is found that the diffraction efficiency of the grating and the intensity of the first-order diffraction can be controlled by controlling the Rabi frequency of the standing wave control field and the interaction length in the quantum well. Optical nonlinearities can improve the diffraction intensity of significant orders, particularly zeroth and first order. The improvement is largest in case only the Kerr is the dominant nonlinearity and moderate under quintic nonlinearity. Present results may be useful in communication and signal processing.
