Mode Optimization and Polarization Control in VCSELs with Sub-Wavelength Gratings
We have demonstrated the integration of sub-wavelength gratings (SWG) into a 795 nm vertical cavity surface emitting laser (VCSEL) with inverse surface relief to achieve coordinated control of the mode and polarization. At a grating period of around 0.5 μm and an etching depth range of 60...
