Abstract
In this paper, we investigate and study the performance of a WDM-based
60 GHz mm-wave fiber-wireless link incorporating a liquid-crystal-on-silicon
(LCoS)-based programmable optical processor (POP) in the remote node (RN)
for demultiplexing and processing of multiple channels. To ensure that the
fiber-wireless link is compatible with existing WDM optical backbones, we
have evaluated the performance of the 60 GHz link using a typical WDM channel
plan with 100 GHz spacing. A number of different filter profiles are investigated
for the POP within the RN and the link performance is quantified and fully
characterized. To demonstrate the robustness and flexibility of the POP as
a RN, we also investigate wavelength-interleaved 60 GHz fiber-wireless link
which requires a more complex filter profile for channel demultiplexing. Our
results demonstrate that the POP allows error-free reception of demultiplexed
channels, though the performance depends on the type of profile used to process
the individual channels.
