We reduce the epitaxial design complexity of our conventional single-cavity oxide-aperture vertical-cavity surfaceemitting lasers (VCSELs) to reduce manufacturing costs while still meeting our internal 980 nanometer VCSEL performance goals via simplicity-in-design principles. We achieve maximum static single-mode optical output powers exceeding 4 milliwatts with small-signal modulation bandwidths exceeding 30 gigahertz at an ambient temperature of about 25 degrees Celsius for VCSELs with an oxide-aperture diameter of about 4 micrometers. Neighbor VCSELs with oxide-aperture diameters above 15 micrometers have maximum room temperature multiple-mode optical output powers of about 20 milliwatts with small-signal modulation bandwidths exceeding 20 gigahertz. The performance of our conventional oxide-confined 980 nanometer simplicity VCSELs exceeds the performance of our previously-reported and more complex 980 nanometer VCSEL epitaxial designs where we previously achieved maximum small-signal modulation bandwidths of about 26 gigahertz with oxide-aperture diameters of about 4 to 6 micrometers.
