Signal distortion in a short wavelength vertical cavity surface-emitting laser (VCSEL) is studied. The spurious free dynamic range is found to be 104.3 dB Hz2/3 at 102 MHz and 98 dB Hz2/3 at 1 GHz, which approaches the dynamic range of Fabry-Perot and DFB lasers, and is 20 dB higher than previously reported for VCSELs.
