Beam　steering　devices　have　wide　applications　in　both　military　and　civil　fields.　The　ultimate　goal　for　such　devices　is　to　reduce　their　size,　weight,　and　power　consumption.　However,　the　laser　source　in　these　devices　is　spatially　separate　from　the　phase　shifter.　resulting　in　large　size,　complex　packaging.　and　low　coupling　efficiency.　To　solve　these　problems,　a　novel　electrically　controlled　beam　steering　chip　based　on　coherently　coupled　vertical　cavity　surface　emitting　laser　(VCSEL)　array　directly　integrated　with　liquid　crystal　optical　phased　array　(LCOPA)　is　proposed　in　this　paper.　Implant-defined　in-phase　coherently　coupled　VCSEL　arrays　(CCVAs)　with　uniform　near-field　are　designed　and　fabricated　first　to　act　as　the　coherent　laser　source　for　the　chip.　Then,　taking　advantage　of　the　CCVA　planar　structure.　the　LCOPA　is　integrated　directly　on　the　CCVA　by　conventional　process.　The　coherent　light　generated　by　the　in-phase　CCVA　is　uniformly　and　normally　incident　into　the　LCOPA　and　is　electrically　steered　by　the　LCOPA.　One-dimensional　beam　steering　is　achieved　by　two　proof-of-concept　integrated　chips.　The　chips　based　on　a　4　x　4　square　CCVA　and　a　16-element　hexagonal　CCVA　offer　a　field　of　view　of　2.21　degrees　and　6.06　degrees,　respectively.　Independent　control　of　the　CCVA　and　LCOPA　guarantees　a　relatively　high　wavelength　stability　and　power　stability.　Theoretical　calculations　arc　also　performed,　which　are　consistent.　whit　the　experiments.　(C)　2019　Optical　Society　of　America　under　the　terms　of　the　OSA　Open　Access　Publishing　Agreement
