To　realize　a　polarization-independent　vertical　cavity　surface　emitting　laser　(VCSEL),　the　polarization-independent　grating　and　the　half-VCSEL　are　integrated.　Based　on　the　rigorous　coupled　wave　analysis,　the　effects　of　grating　parameters　on　the　reflection　characteristics　of　a　polarization-independent　two-dimensional　grating　are　analyzed.　The　210　nm　high-reflection　bands　of　the　polarization-independent　two-dimensional　grating　for　a　grating　period　of　691-719　nm　and　a　grating　width　of　408.73-467.60　nm　are　obtained　via　analog　computation.　Then,　the　polarization-independent　two-dimensional　grating　and　the　half-VCSEL　with　a　1.55-μm　central　wavelength　are　integrated　to　develop　a　polarization-independent　wavelength-tunable　VCSEL　with　the　1.55-μm　central　wavelength.　The　calculation　based　on　an　optical　transmission　matrix　indicates　that　the　wavelength-tuning　range　of　93　nm　can　be　realized　for　the　polarization-independent　wavelength-tunable　VCSEL.　©　2019,　Chinese　Lasers　Press.　All　right　reserved.
