1. A system, comprising:
a first steering layer interposed between an electromagnetic (EM) source and an emission lens, the first steering layer comprising:
a triplet lens comprising a stacked structure comprising, in order:
a Plano-convex lens; and
a first transparent electrode on the Plano-convex lens;
an electro-optical (EO) crystal having the first transparent electrode on a first side thereof;
a second transparent electrode on a second side of the EO crystal, opposite to the first side of the EO crystal; and
a Plano-concave lens on the second transparent electrode;
the EM source configured to provide an EM beam incident upon the first steering layer; and
the emission lens configured to emit a steered EM beam to a target location.
