Abstract
Embodiments of the present disclosure generally relate to a vertical cavity surface emitting laser (VCSEL), a head gimbal assembly for mounting a VCSEL, devices incorporating such articles, and to a process for forming a VCSEL. In an embodiment, a process for forming a VCSEL device is provided. The process includes forming a trench in a substrate, forming two laser diode electrodes in the trench, and after forming the two laser diode electrodes, cutting the substrate along the trench to form a VCSEL, the VCSEL comprising a chip for mounting on a slider, the chip having six surfaces, wherein a first surface of the chip is for facing the slider, a second surface of the chip is opposite the first surface, the two laser diode electrodes being positioned in any combination on one or more of a third surface, a fourth surface, a fifth surface, or a sixth surface.
