1. A beam steering apparatus for adjusting an angle of a light beam, the beam steering apparatus comprising:

  • a first beam steering portion comprising at least two rows of sub-aperture tapered structures configured to controllably steer the light beam in a first in-plane direction using an adjustable index of refraction, wherein at least one row amongst the at least two rows of sub-aperture tapered structures is tipped at a first specified in-plane angle relative to another row amongst the at least two rows, the first specified in-plane angle oriented in the first in-plane direction; and

    a second beam steering portion comprising full-aperture beam steering elements to controllably refract the light beam in the first in-plane direction using an adjustable index of refraction.
