Vertical Cavity Surface Emitting Laser NRZ for Island Use
Because VCSELs emit from the top surface of the chip, they can be tested on-wafer, before they are cleaved into individual devices. This reduces the cost of the devices. It also allows VCSELs to be built not only in one-dimensional, but also in two-dimensional arrays. The larger output aperture of VCSELs, compared to most edge-emitting lasers, produces a lower divergence angle of the output beam, and makes possible high coupling efficiency with optical fibers.
