Abstract
High-performance optical data networks of the future may
interconnect hundreds of users at gigabit rates for a reasonable cost. A
novel approach is described that utilizes a passive star coupler for
distribution, a multiplicity of frequency-shift keyed (FSK) tunable
lasers to provide a frequency division multiplexed (FDM) network, and a
tunable optical fiber Fabry-Perot filter to select the channels and
convert the FSK signal to ASK (amplitude-shift keying) for direct
detection. The design of high-speed FDM-FSK direct detection networks
and the performance of critical devices, such as tunable FM lasers,
tunable filters, integrated star couplers, and optical amplifiers, are
reviewed and discussed
