Micro　electronically　controlled　liquid　crystal　optical　phase　modulators　(LCOPMs)　are　on-chip　integrated　with　partially　coherent　vertical　cavity　surface　emitting　laser　(VCSEL)　array　to　improve　the　array＇s　beam　quality　and　optical　intensity.　The　initial　phase　shift　among　array　elements　introduced　by　imperfect　fabrication　is　compensated　by　adjusting　the　voltages　loaded　on　the　LCOPMs.　Experimental　results　show　that　the　beamwidth　of　the　VCSEL　array　is　reduced　by　28%　and　the　intensity　ratio　of　the　central　lobe　to　the　secondary　lobe　in　the　far-field　is　increased　by　50%　after　phase　compensation　by　the　LCOPMs.　(C)　2019　The　Japan　Society　of　Applied　Physics
