Abstract
In This paper, we have employed a double-ion exchanged diffraction grating, to generate experimentally Fourier spot plane arrays. The grating-length-to-beam-width ratio (d/w0) is found to be an important parameter in determining device performance. With beam width 20μm (W0=20μm), center wavelength of λ=0.6328μm, and changing in interaction length (d) and incident angle several basic results are predicted. We compared our results with the numerical solution using fast Fourier transform beam propagation method (FFT. BPM) and there is a good agreement between them.
