Latest Patents

One of Van Laer's notable patents is the "Acousto-optic beam steering system." This invention discloses systems and methods for steering an optical beam in two dimensions. The system comprises a substrate featuring an acousto-optic antenna array and an acoustic transducer. Each antenna in the array includes a high-confinement surface waveguide that carries a light signal. The acoustic transducer imparts acoustic energy into each surface waveguide as a mechanical wave. The interaction between the light signal and the mechanical wave in each surface waveguide induces light to scatter into free space. The light scattered from the plurality of waveguides collectively defines the output beam. The longitudinal angle of the output beam, relative to the substrate, is determined by the relative frequencies of the mechanical waves and the light signals. The transverse angle of the output beam is controlled by adjusting the relative phases of the mechanical waves and/or light signals across the surface-waveguide array. This innovative approach allows for precise control of optical beams, making it a valuable advancement in the field.
