Abstract
A vertical cavity surface emitting laser (VCSEL) device and a method for manufacturing the VCSEL device without wire bonding process for the topmost positive electrode are disclosed. The device includes epitaxial layer, ohmic contact layer, positive electrode, first insulating layer, conductive layer, and negative electrode. The epitaxial layer includes first and second opposing surfaces, and sidewalls connected to first and second surfaces. The ohmic contact layer is disposed on the first surface and the positive electrode connected thereto is disposed on the second surface. The first insulating layer is disposed on the second surface and extends to the ohmic contact layer along the sidewall. The conductive layer is disposed on the first insulating layer corresponding to the sidewall/sidewalls which carry power for the positive electrode.
