Abstract:
A backside Vertical Cavity Surface Emitting Laser (VCSEL) has a substrate. A first mirror device is formed on the substrate. An active region is formed on the first mirror device. A second mirror device is formed on the active region. A pillar is formed by directional Inductive Coupled Plasma-Reactive Ion Etcher (ICP-RIE). The pillar exposes a portion of the first mirror device, the active region and the second mirror device. A first metal contact is formed over a top section of the pillar. A second metal contact is formed on the substrate. An opening formed in the second metal contact and aligned with the pillar.
