Wavelength　tunable　vertical　cavity　surface　emitting　lasers　(VCSELs)　are　becoming　increasingly　popular　in　wavelength-division　multiplexing　passive　optical　networks　(WDM-PON).　However,　due　to　the　limitations　of　laser　beam　quality,　traditional　designs　find　it　difficult　to　achieve　stable　single　mode　emission　across　the　entire　wavelength　range.　Here,　we　designed　and　fabricated　an　electrically　pumped　1060　nm　heterogeneous　integration　(HI)　super-span　resonance　filtering　micro-electro-mechanical　system　(MEMS)　tunable　VCSEL,　continuously　tuning　34.41　nm　at　room　temperature　and　achieving　single　mode　laser　operation　across　the　entire　tuning　range.　The　linear　polarization　mode　of　the　beam　exhibits　an　almost　ideal　Gaussian　distribution　with　a　minimum　divergence　angle　of　8.65°.　This　work　verifies　the　high　beam　quality　characteristics　of　single　mode　HI　MEMS-VCSELs,　demonstrating　their　potential　application　as　WDM-PON　light　sources　and　providing　new　possibilities　for　various　other　applications.　©　2025　Optica　Publishing　Group　under　the　terms　of　the　Optica　Open　Access　Publishing　Agreement.
