  • Abstract
    We propose the transverse mode control of VCSELs using high contrast sub-wavelength grating (HCG). We found that the angle-dependence of reflectivity of HCG can be controlled by optimizing grating parameters. The active region can be expanded by the highly angular dependent reflectivity.
