Abstract
Closely spaced multiwavelength signals can be efficiently demultiplexed using a single optical preamplifier followed by a single tunable filter (serving as a channel selector and a noise limiter) and a conventional direct-detection front-end.1–3 The performance of such a demultiplexing scheme depends among other things on the interchannel and total power dynamic ranges. The interchannel dynamic range, i.e., the allowed difference in power levels between the transmitted channels, is determined by the filter-induced crosstalk between adjacent channels (and hence is channel separation dependent). The total power dynamic range is determined by the gain saturation characteristics of the amplifier and the amplified spontaneous emission.
