Abstract
as gained a lot of attention alongside advancements
in silicon photonics technology, w hich enables inexpensive
fabrication of a large number of optical components [10], [11].
OPA technology has progressed tremendously within a rela-
tively short period of time, and multiple large-scale implemen-
tations with ∼1000 elements recently reported [12]–[16].
However, it is still challenging to realize a low-cost OPA
that can bring the proliferatio n of chip-scale optical beam
scanners to mass markets.
