摘要：

We　investigate　the　radiation　effects　of　1907　MeV　Ta　ions　on　the　static　and　dynamic　characteristics　of　850　nm　high-speed　vertical　cavity　surface　emitting　lasers　(VCSELs).　The　threshold　current　and　slope　efficiency　are　found　to　be　degraded.　However,　appropriate　ion　fluence　irradiation　can　improve　the　modulation　bandwidth.　The　maximum　3　dB　frequency　is　increased　to　14.02　GHz　from　13　GHz　at　a　fluence　of　1　×　108　ions/cm2.　The　observed　behaviour　can　be　explained　in　terms　of　reflectivity　degradation　of　lossy　distributed-Bragg　reflectors　as　well　as　the　degradation　of　quantum　wells.　©　2021　Elsevier　B.V.
