C. Cox et al., TECHNIQUES AND PERFORMANCE OF INTENSITY-MODULATION DIRECT-DETECTION ANALOG OPTICAL LINKS, IEEE transactions on microwave theory and techniques, 45(8), 1997, pp. 1375-1383
We review state-of-the-art intensity-modulation direct-detection (IMDD
) analog optical links, focusing on advances since 1990, We contrast d
irect and external modulation with respect to gain, noise figure (NF),
and dynamic-range (DR) performance.
