Abstract
Micromechanical tunable VCSELs with dramatically improved performance are demonstrated using AlAs oxidation. Larger aperture (~10 μm) devices achieve record tuning of 19.1 nm with 3.3 mA threshold currents. Smaller aperture (~5 μm) devices achieve record threshold currents of 460 μA, and output powers of 0.9 mW with 7 nm of tuning
