The analog modulation properties of oxide confined InGaAIP vertical cavity
surface emitting lasers (VCSELs) emitting in the visible region (670 nm) ar
e investigated, Two VCSELs with different oxide aperture sizes (10 and 18 m
um) were measured. The larger VCSEL exhibits a spurious free dynamic range
as high as 92-100 dB.Hz(2/3) in the frequency range 0.1-3 GHz while the sma
ller VCSEL exhibits a dynamic range of 88-94 dB Hz(2/3) in the same frequen
cy range.
