Abstract
We demonstrate angular scanning in space of an optical beam, which is coupled out of a nonlinear waveguide via a grating coupler. The output angle is controlled by the power of a second beam, which is coupled into the waveguide via the same grating. The scan angle of the first beam can be made to vary continuously or abruptly, depending on the initial detuning of the second control beam from the coupling resonance.Keywords
