We report on the operational characteristics of hybrid proton implanted/selectively oxidized vertical-cavity surface-emitting lasers (VCSELs) in the 980 nm region. We investigate the output and spectral characteristics of different sized implant/oxide aperture VCSELs. Important operational variables such as current/voltage threshold, output power, efficiency and transverse operating wavelengths are extracted from experiments. A clear correlation is deduced between the sizes of implant and oxide apertures and the output power and lasing wavelength. Moreover, precise choice of implant/oxide dimensions yields a single transverse mode and high output power VCSEL. Finally, we simulate these different sized VCSELs with a vector optical solver (Illinois-VCSEL optical solver) based on a numerical mode-matching method developed by Seurin and Chuang. We successfully compare the experimental spectra with theoretical results and find very good agreement.
