摘要：

Operation　of　a　VCSEL　in　the　fundamental　lateral　mode　is　important　for　free　space　optical　interconnects,　data　communication　through　single　mode　fiber,　and　modulation　spectroscopy.　Unfortunately,　the　VCSEL　has　a　tendency　to　lase　at　multiple　wavelengths.　The　two-dimensional　photonic　crystal　(2-D　PhC)　structure　is　applied　to　lateral　mode　control　of　vertical-cavity　surface-emitting　laser　(VCSEL).　The　characteristics　of　lasing　lateral　modes　in　PhC-VCSEL　were　analyzed.　The　single　lateral　mode　operating　conditions　of　the　VCSEL　confined　by　2-D　photonic　crystal　has　been　obtained.　A　PhC-VCSEL　maintains　single-fundamental-mode　operating　with　output　power　0.6　mW　and　threshold　current　4　mA.　The　full　width　half　maximum　of　the　lasing　spectrum　is　less　than　0.1　nm,　the　far　field　divergence　angle　is　8.4°　and　the　side　mode　suppression　ratio　is　over　30　dB　was　fabricated.　Photonic　crystal　is　an　effective　and　flexible　way　to　control　lateral　lasing　modes　by　introducing　photonic　crystal　confinement　to　top　distributed　Bragg　reflector　of　VCSEL.
