摘要: This study investigates the intensity noise in high-speed vertical-cavity surface-emitting lasers (VCSELs) and its contribution to performance of radio over fiber (RoF) links. We evaluate sinusoidal modulation VCSELs terms second-order harmonic distortion (2HD) third-order intermodulation (IMD3) additions relative (RIN). The spurious-free dynamic range proposed VCSEL is estimated. RoF link assessed by figure. characteristics gain factor (NF) are compared under conventional modulations VCSELs. Also, we present comparison NF between short (300 m) relatively long (2 km) fibers.
