Abstract
A method for steering a beam is disclosed. According to the method, a scene is scanned with a surface emitting grating optically coupled to a free propagation region. The free propagation region is optically coupled to waveguides. The waveguides are disposed at different angles to the surface emitting grating. The scanning includes scanning in a first dimension by cycling through a cross connect to illuminate each waveguide of the waveguides. Scanning in a second dimension is performed by tuning a wavelength of light used to illuminate the waveguides.
