| Popis: | The phase shift between interference pattern and index grating in photorefractive materials affects the coupling between the input beams and hence changes the output. The effect of this phase shift is being analyzed on the redistribution of energy among higher diffraction orders in photorefractive sillenite crystals. The direction of energy transfer with the higher-order beams can be controlled by varying the phase shift. The case of two-wave mixing in transmission geometry is considered. The generation of higher-order beams are also being affected by the ratio of intensities of the two incident beams. The generation of higher orders controlled by various parameters could be utilized for the application of optical interconnects. |
