Abstract：

A　distinctive　method　is　used　to　achieve　transverse-mode　control　by　building　and　integrating　a　tunable　liquid　crystal　(LC)　mode　filter　on　top　of　traditional　vertical-cavity　surface-emitting　lasers　(VCSELs).　An　LC　cell　is　fabricated　by　injecting　a　type　of　nematic　LC　material　(E7)　in　an　annular　groove　patterned　by　SiO2.　By　electrically　tuning　the　refractive　index　of　the　LC,　a　spatially　dependent　reflectivity　profile　can　be　achieved　and　optimized,　which　directly　influences　the　threshold　modal　gain　of　each　transverse　mode　provided　by　oxide-confined　VCSELs.　The　flexible　and　accurate　control　performance　of　the　LC　mode　filter　structure　have　been　demonstrated　by　the　simulation　results　and　our　analysis.　This　design　is　a　completely　novel　method　to　realize　VCSELs　with　an　accurate　and　real-time　controllable　transverse-mode,　and　it　will　probably　play　a　significant　role　in　the　future.　©　2021　Author(s).
