A MEMS optical switch-based LiDAR beam steering unit may comprise an optical switching array comprising two or more translatable optical switch gratings. The two or more translatable optical switch gratings may be arranged in a foveal pattern. Each of the two or more translatable optical switch gratings may have an associated MEMS structure operative to selectively translate the optical switch grating between a first position and a second position, and a first waveguide associated with the translatable optical switch grating. The grating being in the first position may cause the grating to be sufficiently close to the first waveguide to produce a strong optical coupling between the grating and the first waveguide. The grating being in the second position may cause the grating to be sufficiently far from the first waveguide to produce a weak optical coupling between the grating and the first waveguide.

An optical assembly includes a combination of laser sources emitting radiation, focused by a combination of lenses into optical waveguides. The optical waveguide and the laser source are permanently attached to a common carrier, while at least one of the lenses is attached to a holder that is an integral part of the carrier, but is free to move initially. Micromechanical techniques are used to adjust the position of the lens and holder, and then fix the holder it into place permanently using integrated heaters with solder.
