1. A vertical cavity surface emitting laser (VCSEL) device, comprising:
an anode;
a cathode;
one or more curved light-emitting apertures located in an epitaxial layer between the anode and the cathode, each of the one or more curved apertures having an aperture edge;
one or more oxidation bridges crossing the curved aperture that allow current to flow inside the curved aperture; and
one or more oxidation regions separating the apertures;
wherein 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.
