We have designed and fabricated and VCSEL arrays at 850 and 980 nm operation wavelength, respectively, which are designed for maximum single-mode output power and high-frequency applications. GaAs VCSELs in the array show record high single-mode CW powers up to 4.8 mW. Individual devices of the InGaAs VCSEL array exhibit small-signal modulation bandwidths exceeding 10 GHz.
