Abstract
Systems and methods disclosed herein include a vertical cavity surface emitting laser (VCSEL) device that includes an anode, a cathode, and one or more curved apertures located in an epitaxial layer between the anode and the cathode, each of the one or more curved apertures having an aperture edge and one or more oxidation bridges crossing the curved aperture that allow current to flow inside the curved aperture, in which when a current signal is applied to the VCSEL, current flow between the anode and the cathode is distributed along the aperture edge of the one or more curved apertures.
