30-GHz small-signal modulation bandwidth with directly current-modulated 980-nm oxide-aperture VCSELs
Directly current-modulated 980-nm vertical-cavity surface-emitting lasers (VCSELs) with oxide-aperture-diameters of 1.5-micrometers exhibit small-signal -3-dB modulation bandwidths of 31 and 25-GHz and maximum single-mode light-output-powers of 3 and 2-mW at 25 and 85°C, respectively. The side-mode-suppression-ratio exceeds 40-dB at bias currents above threshold.
