Transparent ROF link using EA modulators

Transparent analog fiber link is the key element to many radio-over-fiber applications such as antenna remoting and CATV. In this paper, we present the performance of analog fiber link using advanced design of electroabsorption modulator that incorporates peripheral coupled waveguide (PCW) and intra-step-barrier quantum well (IQW) designs. High efficiency PCW-IQW electroabsorption modulator with high optical power handling property will be presented. The resultant transparent analog fiber link can be used for achieving high spurious free dynamic range.
