Description
Summary:An optical phase grating has been generated by introducing surface waves on one face of a Fabry-Perot interferometer. This device called SWIM (Surface Wave Interference Modulator) produces a diffraction pattern at the Fourier plane in which the light intensity of the first-order modulated beam is 1% of the zeroth order with an acoustic power of 0.85 mW/mm beam width. First-order intensities greater than 10% have been realized; however, the process is not linear at this modulation depth.
